摘要:
Zinc and cadmium pyridine-2-thionato complexes, M(pyt)2, were prepared by direct electrochemical oxidation of the metal into a solution of pyridine-2-thione (pytH) in acetonitrile. Adducts of type [M(pyt)2L] (L = 2,2'-bipyridine or 1,10-phenanthroline) were obtained by addition of the ligand to the electrolyte phase. X-ray structure determination of [Zn(pyt)2phen] shows the molecule to have a distorted octahedral trans-ZnS2N4 core, with average bond distances of 2.182 angstrom for Zn-N(phen), 2.061 angstrom for Zn-N(pyt) and 2.586 angstrom for Zn-S. The vibrational, H-1 and C-13 NMR spectra of the compounds are discussed.
