Exchange studies with the metal ions show binding preference in the order of NiII>CoII/CuII>ZnII. The compounds were confirmed by NMR, UV-Vis studies and the X-ray crystals structures of [Co(L1)](PF6)2, [Ni(L1)](PF6)2, [Cu(L1)]ClPF6, [Zn(L1)](PF6)2, and [Ni(L2)]Cl2. In the solid state, the arrangement of the bulky pyrazole units leads to the formation of two distinct cationic pockets containing the N−H groups of the pyrazoles. These cationic pockets are found to bind Cl− or PF6− counterions through hydrogen bonding and anions titrations revealed good affinity for Cl− and Br−. The compounds can be dehydronated up to two times using mild organic bases, highlighting the potential of these ligands to tune the electronic properties of the metal center.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 11","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822154","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}

Another 78 years have passed since then. This provides a good occasion to pinpoint what we know and what we still do not know of this radioelement. Technetium is placed near the center of the Periodic Table, in the center of the groups 6, 7, and 8. Some chemical properties of the elements surrounding technetium show trends within the columns or along the rows of the Periodic Table, but a consistent interpretation of these trends is lacking as long as the knowledge on technetium remains incomplete. This is especially remarkable as, on the other hand, the isotope 99mTc is applied on a daily basis in nuclear medicine. The aim of this paper is to review the fundamental understanding of technetium chemistry, mostly focusing on the research of the last decade, its implications, and its future perspectives. These developments show a picture of growing connections between physicochemical data, fundamental inorganic chemistry, organometallic and coordination chemistry, computational chemistry, and geochemistry.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 9","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.202400780","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699028","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 the present work, a new cobalt(II) complex compound with an unusual and rare structure, not previously described in the literature, was synthesized. This complex has two 2,2′-bipyridyl ligands, a water molecule and, most interestingly, a sulfate(VI) anion in the Co(II) coordination sphere. Its use and catalytic properties were studied in the oligomerization of selected olefins, where it acted as a precatalyst. The achieved catalytic activity values were rather high (<100 g mmol−1 h−1 ⋅ bar−1), except for the oligomerization process of 2,3-dibromo-2-propen-1-ol using MAO. The obtained oligomers were subjected to structural (FT-IR, SEM, MALDI-TOF-MS) and thermal (TG, DSC) analysis, and the results allowed to characterize their physicochemical properties. The conducted process allowed to determine the effect of the applied activator on the catalytic activity, as well as the structural and thermal properties of the obtained oligomers. In addition, the specific surface area and sorption properties of the oligomerization products were studied, and one of them showed very high CO2 sorption values (<1.6 mmol g−1).","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 11","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822200","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}

To overcome this limitation, we previously developed a dinuclear Zn(II) complex that absorbs visible light through an empty σ orbital formed between two proximal Zn atoms and exhibits dual emission at 77 K. However, the roles of the central metal atom in influencing the structural and photophysical properties were not fully investigated. In this study, we synthesized a dinuclear Cd(II) complex, structurally analogous to the Zn(II) complex, to investigate the effects of the central metal atoms on these properties. Structural analyses revealed that both complexes are highly similar, with slightly elongated Cd–Cd distances because of Cd's larger van der Waals radius. Theoretical calculations indicated attractive intermetallic interactions between the central metal atoms in both complexes. Although both complexes displayed negligibly different visible light absorptions, the Cd(II) complex displayed a much higher intersystem crossing rate than the Zn(II) complex, generating distinctly different overall emission profiles. These findings emphasize the crucial roles of the central metal atoms in influencing the structural and photophysical behaviors of dinuclear complexes, providing deeper insights for designing group-12-element-based materials.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 7","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.202400666","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564978","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, a series of Cu-SAPO-34 catalysts with varying Cu contents were synthesized by the one-step hydrothermal method. The physicochemical properties of the catalysts were investigated by characterizations, and the reasons for the well-activity catalysts were analyzed. The acidic sites on the SAPO-34 zeolite can adsorb and activate NH3, while the copper active sites can promote the activation and reduction of NOx, accelerating the reaction process of SCR. In this study, Cu-SAPO-34 with Cu content of n(Cu)/n(C9H21AlO3)=0.075 has good framework stability, which produced more free Cu2+ ions and the Cu species are evenly distributed on the carrier surface, and the appropriate amount of acid sites.
