Structural characteristics of the obtained compounds were determined using X-ray diffraction data. The magnetic susceptibility and EPR data of the new Gd complexes are considered taking into account the features of their composition and structure. Due to the peculiarities of the electronic structure, Gd complexes can serve as test systems for analyzing the field strength of ligands and the geometry of the local environment of the 4f-metal ion. It is shown that EPR spectroscopy is highly efficient method for determining the spin Hamiltonian parameters and, consequently, for characterizing the local environment of the gadolinium ion in complexes. However, the EPR method does not allow one to determine the sign of the splitting parameter in the zero field D, which requires additional studies.","PeriodicalId":759,"journal":{"name":"Russian Journal of Coordination Chemistry","volume":"50 4","pages":"246 - 256"},"PeriodicalIF":1.1,"publicationDate":"2024-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141778729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The crystal structures of the ligand and complex III are determined by X-ray diffraction (XRD) analysis of single crystals (CIF files CCDC no. 2298715 (L) and 2298716 (III)). Complex III is polymeric due to the bidentate-bridging coordination of the ligand by the oxygen atoms of the cyclohexanedione fragment, and the coordination number of the central atom is ten. According to the powder XRD data, all synthesized polycrystalline compounds are isostructural to the single crystals of complex III. The photoluminescence properties of the ligand and coordination compounds in the polycrystalline state are studied. The energy transfer from the ligand to lanthanide(III) ion is shown to proceed via the “antenna” mechanism in the case of the europium(III), samarium(III), and terbium(III) compounds.
