The metal complexes of Ca^II, Co^II and Cull with Schiff base of cephalexin (salicylidene cephalexin) of the type ML₂ (where M = Ca^II, Co^II or Cu^II and L = Schiff base of cephalexin) have been prepared via Schiff have obtained by the condensation of cephalexin with salicylaldehyde. They form 2 : 1 ligand to metal complexes with Ca^II , Co^II and Cu^II, as indicated by conductometric titrations. The complexes have been characterized by various physicochemical techniques such as elemental analysis, molar conductance and spectral analysis such as mass. UV and JR.
