Such transformations are considered separately for the formation of both paramagnetic and diamagnetic coordination complexes. A section discussing the features of nuclear magnetic resonance in paramagnetic systems precedes the discussion of the molecular structure of specific organic heteroatom compounds and their complexes. These features arise from hyperfine interactions between unpaired electrons localized on the coordinating ion and the resonating nuclei. This results in paramagnetic line broadening and contact and pseudocontact shifts of resonance lines in nuclear magnetic resonance spectra. These paramagnetic shifts and broadenings provide information on molecular structure. The main principles of the paramagnetic additive method are presented; their use enables overcoming difficulties associated with strong paramagnetic broadening of resonance lines in high-resolution nuclear magnetic resonance spectra.

The molecular structure of the tetraphenylsilyl-based complex (<b>5a</b>) was established by single-crystal X-ray diffraction. Although crystals of the germanium analogue (<b>5b</b>) were unsuitable for direct structural analysis, powder X-ray diffraction confirmed its phase purity and demonstrated its isostructural to the silicon complex. These results expand the coordination chemistry of silicon- and germanium-substituted diketone ligands and illustrate their potential for constructing new Cu(II) coordination architectures.</p>","PeriodicalId":759,"journal":{"name":"Russian Journal of Coordination Chemistry","volume":"51 12","pages":"1118 - 1124"},"PeriodicalIF":1.1,"publicationDate":"2026-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588504","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}
