Utilizing a variety of computational methods, including density functional theory and multireference electron correlation techniques, we examine the influence of various substituents on the electronic structure and stability of cobalt complexes. Our findings reveal that strong electron-withdrawing groups enhance the formal redox potential, while electron-donating groups decrease it, illustrating the delicate balance between electronic effects on the complex stability. The simulated properties were compared with the available experimental measurements, demonstrating good correlation and validating the computational approaches used. Analysis of the spin states indicates that cobalt(II) complexes predominantly exist in a high-spin state with low-spin configurations favored in cobalt(III). The reorganization energy for these complexes was calculated, highlighting the role of the inner and outer-shell contributions in determining electron transfer kinetics.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"4 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The alignment of hexagonal windows (8.3 × 8.3 Å2 in cross-section) across the stacked layers forms straight pseudochannels that enables effective ion diffusion and accommodation. SnS-1 exhibits outstanding ion exchange kinetics (k2Cs = 0.256 g mg-1 min-1; k2Sr = 0.272 g mg-1 min-1) and capacities (qmCs = 417.24 mg g-1; qmSr = 116.18 mg g-1), exceeding most chalcogenide-based exchangers. It exhibits acid-base resistance across a broad pH range (0-11) and remarkable selectivity for Cs+ and Sr2+ over various competing ions. Dynamic column filtration confirms the separation applicability of SnS-1, featuring sustained Sr2+ removal (RSr = 94.45-99.51%) against Cs+ (RCs = -20 ± 5%). The SnS-1/PTFE composite membrane can efficiently remove Cs+ and Sr2+ from continuous flow (2.0 mL min-1 cm-2), with removal efficiencies exceeding 91.71 and 98.91%, respectively. Moreover, the adsorbed Cs+ and Sr2+ ions can be readily eluted from the spent column and membrane using a 2 M NaCl solution. Combined with simple synthesis, radiolytic stability, and superior performance, microporous SnS-1 emerges as a promising candidate for nuclear wastewater remediation.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"153 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To our knowledge, this study provides the first detailed absorption spectra of Am(III) spanning the entire UV/vis/NIR region in these mineral acids reported since the 1960s. Using this high-resolution absorption data, provided in an open access format for the broader field, we build on prior work by Carnall and others to provide detailed optical analysis including all transition assignments. This work also includes the first reported absorption spectrum of Am(III) in aq. HBr. Characteristic Am(III) luminescence could be detected from all three samples. These are the first reports of emission from Am(III) in these acid systems, which build on prior emission reports collected from aq. HClO4 solutions. The acquired emission spectra display anion-dependent shifting of the visible-region transitions by up to 21 nm from their predicted positions, akin to the nephelauxetic effect. The shift magnitude trends linearly according to acid pKa and more generally according to the transition metal spectrochemical series. These ligand field effects, coupled with luminescence lifetime experiments, indicate that weak Am-X interactions persist in solution.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"34 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, a new type of S-X long bonds, which are significantly longer than traditional S-X covalent bonds, has been discovered. The P,N-ligated Ni-F complex model 1A can bind a SO2 molecule through the new F-S long bond (2.207 Å), and a stable Ni-F-SO2 complex 1B is generated, being exergonic by 2.2 kcal/mol. According to natural localized molecular orbital analysis, the new S-F long bond has a unique p(F) → π*(O═S═O) bonding interaction, which is shown to arise from the long S-F length. In comparison, the strength of the new F-S long bond (-2.2 kcal/mol) is found to be significantly stronger than common noncovalent interactions such as the hydrogen and halogen bond. The substituent modulations suggest that the electron-donating groups can increase the strength of new F-S bonds and enhance binding free energies ΔGbind. The scope of possible M-X complexes was explored, and various metals and X (F, Cl, and H) ligands were found to form stable M-X-SO2 complexes. Specifically, the anionic M-X complexes display much higher ΔGbind values, ranging from -8 to -10 kcal/mol. The study paves the way for a green, recyclable, and adjustable SO2 absorption method.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"3 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because the structures of the ground state oligomers have linear staggered structures, the photoexcited oligomers generated in these crystals are also expected to have linear staggered structures. The crystals exhibit emission, in which the dominant emission bands are located at 430 nm in 1 and 400 nm in 2 at 77 K with emission quantum yields of unity. These emission bands at 77 K were assignable to the phosphorescence of the tetramer and trimer of linear-staggered structures because they resemble the phosphorescence of the trimer and tetramer in aqueous solutions. The radiative lifetimes of the T1 trimer and T1 tetramer were estimated as 0.9 and 1.6 μs, respectively, from their quantum yields and lifetimes. The emission lifetime of 2 was observed in the temperature region of 4-110 K to estimate the zero-field splitting of the lowest triplet state of the trimer as 36 cm-1 (EI-II) and 64 cm-1 (EI-III) and the radiative rate constants of the three states as 1.43 × 103 s-1 (kI), 2.0 × 104 s-1 (kII), 4.8 × 106 s-1 (kIII).","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"5 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
