Complexes of type ML₂X₂, where L = 2-(o-anisylidineiminoamino)-4-phenylthiazole (APT) or 2-(o-anisylidineiminoamino)-4-(p­bromophenyl)thiazole (ABPT); M = Co^II, Ni^ll, Cu^II) have been synthesised. The results are consistent with bidentate chelation of the ligand with azomethine nitrogen and ring sulfur atoms as bonding sites, the complexes are in an approximately octahedral environment. The symmetry being C₂ for the Co^ll complexes and D_4h for other complexes. Crystal field parameters for the Co^ll and tetragonal parameters for the NI^II complexes have been calculated.
