In this work, three monoclinic silver(I) complexes [Ag(L1)2]NO3 (1), [Ag(L1)(L2)]NO3 (2), and [Ag(L2)2]NO3 (3) (where L1 = (1-methyl-1H-benzimidazol-2-yl)methanol and L2 = (1-ethyl-1H-benzimidazol-2-yl)methanol) characterized similar coordination environments of Ag(I) centers based on single-crystal X-ray diffraction. However, their solid-state fluorescence properties exhibited significant differences. Specifically, the emission peak of complex 1 was redshifted by 141 nm relative to L1, while the emission peak of complex 2 was redshifted by 94 nm relative to L1 but blueshifted by 71 nm relative to L2. In contrast, complex 3 showed a blueshift of 93 nm compared to L2. This opposite shift direction arises from whether the bandgap narrows (for L1) or widens (for L2) upon Ag(I) coordination, as governed by the interplay of electron-donating strength and steric hindrance of the side groups. These differences were primarily attributed to the fine-tuning of the electronic structures, intermolecular interactions, and excited-state charge distributions induced by the side-group of ligand. This finding indicates that ligand side groups not only influence the emission wavelength of the free ligands but also determine the trend of photophysical property changes upon complex formation.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 29","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149125794","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}

MOFs are associated with different promising properties like high surface area, tunable pore structure, and significant chemical functionality that make them an attractive class of heterogeneous catalysts. The modular nature of MOFs allows for design control over their active sites within the catalytic framework. Among transition metals, manganese (Mn) has received significant attention for several reasons, including the existence of multiple accessible oxidation states (Mn2+, Mn3+, and Mn5+), high redox activity, modest toxicity, and low cost. These benefits allow Mn-MOFs to mediate a suitable host of organic transformations, such as oxidation, condensation, and multicomponent coupling reactions, under mild, green, and sustainable catalytic conditions. The combined features of the tunable structure common in MOFs and the flexible redox behavior led to enhanced catalytic performance, stability, and reusability of Mn-MOFs. This review describes the detailed catalytic applications and mechanistic aspects of Mn-MOFs for sustainable organic transformations developed over the past 15 years.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 29","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149125847","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}

Variable-concentration NMR and UV–vis absorption measurements demonstrated pronounced self-association of the Ni(II) and Pd(II) complexes in solution, affording dimerization equilibrium constants of 432 and 272 L mol−1, respectively. In contrast, the corresponding salophen complexes lacking the naphthodithiophene unit showed only weak self-association, indicating that extension of the π-conjugated surface markedly enhances intermolecular π–π interactions. Furthermore, introduction of bulky tert-butyl substituents effectively suppresses dimer formation through steric hindrance.

Among low-valent main-group compounds, tetrylenes (R2E:, E = Si, Ge, Sn, Pb) occupy a central position because their ambiphilic electronic structures enable diverse bond activation and coordination chemistry. Although adjacent low-valent Group 14 systems, including 1,2-bis(tetrylene)s, ditetrynes, and related heavier alkyne-type compounds, have been widely investigated as cooperative platforms, 1,3-bis(tetrylene)s remain comparatively underexplored. In this review, we summarize recent developments in 1,3-bis(tetrylene) chemistry, with emphasis on synthesis, structure, electronic properties, and reactivity. The discussion is organized according to the identity of the bridging atom, covering systems bridged by pnictogen, chalcogen, and tetrel (Group 14) elements. By comparing these bridge motifs, we highlight how electronic stabilization, steric protection, and geometric constraint govern the balance between stability and reactivity. Finally, we discuss future opportunities for using 1,3-bis(tetrylene)s as cooperative main-group platforms for bond activation, ligand design, catalysis, and the construction of heavy-element π systems.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 28","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.70309","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068420","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}

Although Zr(IV) hydrolysis has been extensively studied, its behavior under radiolytic and actinide-containing acidic conditions remains poorly understood. Here, we investigate the hydrolysis and coordination chemistry of Zr(IV) in 2 M H2SO4 both in the absence and in the presence of γ-radiation and U(VI). In 2 M H2SO4, Zr(IV) forms amorphous Zr(IV)–SO42−–OH aggregate driven by sulfate coordination. γ-Irradiation reduces aggregate size without significantly altering the local Zr coordination environment, as confirmed by transmission electron microscopy (TEM) and extended X-ray absorption fine structure (EXAFS) measurements. Under electron-beam irradiation during TEM imaging, these aggregates undergo decomposition followed by crystallization. In situ electron-beam mass spectrometry indicates that radiolysis of aqueous components promotes atomic rearrangement and generates a localized reducing environment, leading to ZrS2 formation. The presence of U(VI) alters the Zr(IV) coordination environment and inhibits Zr(IV)–SO42−–OH aggregates formation. Upon γ-irradiation of mixed Zr(IV)/U(VI) solutions, cubic-shaped amorphous U(VI)–Zr(IV)–SO42−–OH assemblies are formed, likely through OH•-mediated coordination and aggregation processes. These findings provide new insights into the coordination chemistry and radiolytic aggregation behavior of Zr(IV) in highly acidic actinide-containing environments.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 28","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068082","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}

From this perspective, a distinctive reactivity emerges, revealing the possibility of obtaining homohalide derivatives containing three bromide ligands under different experimental conditions, depending on the nature of the halide in the initial linear complex. This reactivity implies a redox process with an electron transfer between the halide ligand and a Br2 molecule. Detailed DFT calculations reveal the occurrence of the inverted ligand field for all square-planar products and intermediates.
