摘要:
Cobalt(II), nickel (II), copper(II), zinc(II), cadmium(II) and lead(II) complexes of isatin 3-hexamethyleneiminylthiosemicarbazone, [M(Ishexim)(2)](5), as well as a thallium(I) complex, [T1(Ishexim)], have been prepared by electrochemical synthesis. The crystal structures of [Zn(Ishexim)(2)] and [Pb(Ishexim)(2)] have been solved, and the metal complexes have been characterized by their H-1 and C-13 NMR, IR, UV-Vis and mass spectra. Coordination of the Ishexim anions is via the imine nitrogen and thiolato sulfur atoms with evidence for weak interaction of the amide oxygen with the isatin portion of the ligand.
