The preparation and characterization of new mercuric complexes of formula L(2)Hg(CN)(2) with L being imidazolidine-2-thione (Imt) and its substituted derivatives, 1,3-diazinane-2-thione (Diaz), 1,3-diazipane-2-thione (Diap), are described. The solution and solid-state (13)C NMR show a significant shift of the CS carbon resonance of the ligands, while the other resonances are relatively unaffected,
分子式为L(2)Hg(CN)(2)的新汞配合物的制备和表征,其中L为咪唑烷-2-硫酮(Imt)及其取代的衍生物1,3-二氮杂环丁烷-2-硫酮(Diaz),描述了1,3-二氮杂环庚烷-2-硫酮(Diap)。溶液和固态(13)C NMR显示出配体的CS碳共振的显着偏移,而其他共振相对不受影响,表明最有可能在溶液中保持固态结构。从固态NMR数据确定(199)Hg屏蔽张量的主要成分。游离配体及其配合物的抗菌活性研究表明,与其Hg(II)配合物相比,配体显示出显着的抗菌活性。
