Electrochemical synthesis and crystal structure of zinc(II) complexes with N2N′2S2 amide–thioether hexadentate ligands.

Three novel complexes of zinc with hexadentate amide–thioether ligands were synthesized by electrochemical oxidation of zinc in dichloromethane–methanol solution. These compounds were characterized by elemental analyses, 1H NMR, and IR spectroscopy. The molecular structures of two complexes were determined by single crystal X-ray diffraction, indicating that, the metal atom is in a distorted octahedral environment with amide–thioether ligand acting as a hexadentate N2N′2S2 donor
