A series of novel metal complexes of Schiff bases have been prepared by the interactions of Cu (II) with 1,3 - di hydro - 3 - [2-(Phenyl) – ethylidene]-2H-indol-2-one-hydrazine carboxamide in bimolecular ratios. All the new compounds have been characterized by elemental analysis, conductance measurement, magnetic moment determinations, IR, UV and NMR spectral studies and thermal studies. The physio-chemical studies and spectral data indicate that the ligand acts as a bidentate chelating ligand coordinating through nitrogen and oxygen atoms. Square planar geometry is proposed for all the complexes.
