Abstract
Cobalt(II) complexes of five 4-acetamidobenzaldehyde N(4)-substituted thiosemicarbazones have been prepared in EtOH solution and characterized by i.r., electronic and n.m.r. spectra, and by magnetic susceptibilities and molar conductivity measurements. The thiosemicarbazones coordinate as monoanionic or neutral ligands via the thiosemicarbazone azomethine nitrogen and thione/thiolato sulfur, the latter by loss of the thioamide hydrogen, N(2)H. The resulting cobalt(II) complexes exhibit a varied stereochemistry.[PUBLICATION ABSTRACT]
