1070-1072A 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.</span
