A series of metal complexes of Mn(II) and Zn(II) have been synthesized with newly synthesized biologically active ligands. These ligands were prepared by the condensation of substituted 2'-Hydroxyacetophenones and piperonal. The structure of the complexes have been proposed by analytical data, conductivity measurement, magnetic moment, IR, electronic spectra and thermal studies. Analytical data confirmed 1:2(metal : ligand) stoichiometry and the electronic spectral data suggest that all Mn(II) complexes are octahedral geometry.
