Abstract: A new ligand, 1,3 -disuccinimido(4-phenyl-5-ethoxycarbonyl- 6-methylpyrimidine-2-one) L, has been synthesized by the interaction of 4-phenyl -5-ethoxycarbonyl-6-methyl-1,3 -dihydropyrimidine- 2-one with N-bromosuccinimide. Its metal chelates with Cr(III), Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) have been characterized by elemental analysis, IR & electronic spectra,  molar conductance and magnetic measurements. The molar conductance values suggest that complexes of divalent metal ions are covalent while those of trivalent metal ions are 1:1 electrolytes. The electronic spectra and magnetic moment measurements indicate that all the complexes have octahedral geometry. The β values show a considerable orbital overlap between M-L bond.
