Herein, the solvothermal method is employed to synthesize the HKUST-1 MOF, using single-solvent systems and mixed-solvent systems (DMF, ethanol, water, and acetonitrile) in order to understand their impact on the framework properties. The results demonstrated that modifications in the solvent system exceptionally altered the crystallite size (ranging from ∼31 to 79 nm), morphology, and textural properties while maintaining the core framework. Fascinatingly, PD has the largest surface area, measuring 1145.5 m2/g, with a total pore volume of 0.46 cm3/g. Yet, the CO2 adsorption performance test carried out at 298 K and up to a pressure of 1 bar followed the trend: DE > EW > PD > DW > AE > PE > AW. The performance of DE has been attributed to its significant open Cu2+ binding sites, crystallite size, and engineered pore structure that leads to the CO2 adsorption of 3.58 mmol g−1. Lastly, a regeneration test on the best-performing material (DE) indicates that it can maintain up to 75% of its initial capacity, suggesting that it can be reused for at least three cycles. Ultimately, these findings suggest that solvent-mediated synthesis impacts the overall characteristic features of the material, leading to variation in the adsorption capacity.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 25","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148862327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rational exploitation of the chemical parameter space enables the tuning and control of these morphological features. This study presents a systematic investigation of conventional and microwave-assisted hydrothermal syntheses of ceria nanorods and nanocubes. The specific role of Ce(III) counter-ions in nanorod formation was systematically investigated, identifying chloride ions as essential for anisotropic growth. Microwave heating proved superior to conventional methods, yielding high-aspect-ratio rods in 10 min while preventing the surface area loss associated with thermal coarsening. For the nanocubes, an acid-buffered route was developed to narrow the polydispersity. The reactor filling ratio in the microwave syntheses emerged as a key parameter to modulate solvent evaporation, allowing tuning of the nanocube size (from 14 to 26 nm) and truncation degree. Structural and morphological characterisation by X-ray diffraction (XRD), transmission electron microscopy (TEM) and Brunauer–Emmett–Teller specific surface area analysis (BET) confirmed the formation of highly crystalline and porous nanomaterials, providing a rational framework for the synthesis of ceria nanostructures with controlled morphology via microwave-assisted heating. The effect of autogenous pressure was rationalised by numerical calculations using a Python script developed by the authors.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 25","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.70287","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148862512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oxidation of [1.1]ferrocenophane with DDQ afforded [1.1]ferrocenophane-1,12-dione. Here, new results of the chemistry of this compound are reported. One electron oxidation gave the mixed valence Fe(II)/Fe(III) monocation, which was characterized by its Mößbauer spectrum. Knoevenagel condensations of [1.1]ferrocenophane-1,12-dione with malonodinitrile and cyanoacetic acid esters in the presence of a Lewis acid gave a number of mono- and di-condensation products, all of which showed a syn conformation. While condensations with malonodinitrile afforded the mono- and the di-condensation products, less symmetric substrates such as tert-butyl cyanoacetate gave mixtures of diastereomers. At elevated temperatures decarboxylation reactions gave cyanomethylene substituted [1.1]ferrocenophane derivatives as diastereomeric mixtures, which could chromatographically be separated. An attempted McMurry reaction of [1.1]ferrocenophane-1,12-dione did not result in an intramolecular coupling but in an intermolecular combination. Finally, the reduction of [1.1]ferrocenophane-1,12-dione with lithium tetrahydridoaluminate followed by aqueous work up gave a small yield of an intramolecular etherification product. In eight cases, the reaction products were characterized by crystal structure analyses.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 25","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.70280","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148862382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data reveal the formation of the oxygen-rich intermediate Ho2H0.50O2.75, which was isolated after reaction and structurally characterized by Rietveld refinement as isotypic with the corresponding yttrium compound. The starting phase HoHO shows a limited oxygen solubility that can be described by HoH1−xO1+x/2 with 0 ≤ x ≤ 0.1, while the intermediate Ho2H0.50O2.75 exhibits rapid ordering of the partially occupied O2 and O4 sites toward occupancies of about one half and no clear evidence for a phase width on the hydrogen-richer side. Thus, the first anion-exchange step proceeds closely analogously to that previously observed for YHO. In contrast, the further transformation to Ho2O3 occurs over a comparatively narrow temperature range because the tetragonal metrics of Ho2H0.50O2.75 progressively approach cubic symmetry and increasingly overlap with those of holmia. The results establish Ho2H0.50O2.75 as the key intermediate in the oxidation of HoHO and highlight both the generality and the methodological limits of tracking anion-exchange processes by in situ neutron diffraction.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 25","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.70288","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148862511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While previous studies consider the substituent effect of the phosphine oxide, few theoretical studies have addressed the silane influence over the reaction. For this reason, free energy barriers for the hydrogen transfer step were calculated and analyzed using the distortion–interaction model and natural bond orbital (NBO) theory. Our analysis of R3SiH silanes indicated that the highly acidic silanes Cl3SiH and (OCN)3SiH readily reduce Ph3PO. Further analysis revealed that Ph2RSiH derivatives (RCl, OCN) also exhibit low activation barriers. NBO analysis showed that the presence of a small electronegative substituent directly bonded to silicon (e.g., Cl, OH) enhances donation from the oxygen lone pair, n(O), into the σ*(SiH) and σ*(SiR) orbitals. This stabilizes the interaction energy and as a result lowers the computed energy barrier. These findings provide a unified electronic framework for phosphine oxide reduction and offer practical design principles for efficient silane reagents.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 24","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.70282","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148754248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, ZnO/BiOI heterojunction composites were synthesized via a two-step hydrothermal method and applied to the photocatalytic degradation of metronidazole (MNZ). The effects of key experimental parameters on degradation efficiency were systematically investigated, including pH, catalyst dosage, and initial pollutant concentration. Under optimal conditions, the photocatalytic performance of a series of ZnO/BiOI composites toward MNZ degradation was evaluated. All composite samples exhibited markedly higher photocatalytic activity than the individual components. The ZB0.2 composite achieved an MNZ degradation rate of 90.7% after 4 h of light irradiation, which was 19.8% and 14.9% higher than those of ZnO and BiOI, respectively. The enhanced photocatalytic performance was attributed to the formation of a p–n heterojunction in ZnO/BiOI, which promoted efficient charge separation and transfer. Three coexisting reaction pathways were proposed to account for the efficient mineralization of MNZ.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 24","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148754250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report the synthesis of a series of backbone functionalized imidazolium precursors incorporating chloromethyl, azidomethyl, triazole–steroid, and pyridinium motifs, introduced to enable postfunctionalization, exploit the bioactive and bio-orthogonal properties of azides, confer potential hormone-receptor interactions through a steroidal fragment, and promote mitochondrial targeting through a lipophilic cationic unit, respectively, while maintaining steric protection around the metal binding site. These precursors were efficiently converted into Cu(I)–NHC complexes via a weak-base protocol and into Ru(II)–arene carbonato and dichloro NHC complexes using an analogous methodology, highlighting operationally simple, scalable approaches suitable for sensitive or multifunctional ligands. Structural characterization confirmed the formation of well-defined metal–carbene species. Biological evaluation revealed that Cu(I)–NHC complexes exhibit potent antiproliferative activity against ovarian (A2780, A2780cis) and breast (MCF-7) cancer cells, including cisplatin-resistant models, and induce apoptosis with moderate selectivity over nontumorigenic keratinocytes. In contrast, Ru(II)–NHC complexes displayed moderate cytotoxicity but are consistent with profiles favoring anti-metastatic and mechanistically distinct actions.
