Polymetallic complexes: part VII. bis(benzoin)thiocarbohydrazide complexes of cobalt(II), copper(II) and zinc(II)

Summary Complex compounds of cobalt(II), copper(II) and zinc(II) with bis(benzoin)thiocarbohydrazide have been synthesised. The ligand is probably coordinated to the metal ions as an ONNO tetradentate donor, giving rise to binuclear metal complexes with a halogen bridge. Structures have been assigned on the basis of analyses, conductance, magnetic susceptibility, i.r., electronic spectra and molecular weight data.
