ABSTRACT:

Ti(III),Mn(III) & Co(III) complexes of schiff bases derived from condensation reaction of 3-(2-amino-4-thiazolyl)coumarin with 2-hydroxybenzaldehyde,2-hydroxy-3-methoxy benzaldehyde and 2-hydroxy-1-napthaldehyde have been prepared and characterised. All the three ligands function as uninegative bidentate coordinating ligands with metal ions through phenolic oxygen and azomethine nitrogen. The complexes have been characterised by analytical data, molar conductance, magnetic susceptibility, electronic and infra red spectra. Based on these studies octahedral geometry has been proposed for these complexes.

KEYWORDS:
