Preparation, Identification and screening biological activity of ligand and Metal Complexes of Co(II), Ni(II), Cu(II), Pd(II) and Pt(IV)

A new chain of conversion metal complexes of Co(II), Ni(II), Cu(II), Pd(II),and Pt(IV), with mercaptoacetamide (H2L) N,N -(3,3 -dimethyl[1,1 -biphenyl]-4,4 -dil)bis(2-mercaptoacetamide) ligand, type (N2O2S2) were prepared by condensation of (o-Tolidine) with(mercaptoacetic acid), by (2:1) metal to ligand molar ratio. The complexes were characterized by elemental analysis, magnetic susceptibility, molar conductance , IR , 1H NMR and UV-Vis spectral means. From the spectroscopic studies, Melting points, magnetic moments, physical properties and mole ratio, we suggested the octahedral Cobalt(II) , Nickel (II) , Copper(II) and Platinum(IV) Complexes with ligand and the square planar geometry suggested for Palladium (II) complex. The results submit that the metal is connective with the ligand during the carbonyl oxygen of amide (C=O), the amine group (N-H) and the (S-H) group.
