Abstract

A facile synthesis of the above titled homogeneous mixed ligand complex is reported. The reaction of equimolar mixture of copper (Cu) and molybdic acid (MoO3 . H2O) powders with an aqueous solution of glycine (Hgly) and imidazole (Him) in excess hydrogen peroxide (H2O2), at ambient conditions results in the formation of novel complex [Cu, Mo(O)(O-2(2-))(gly)(2)(Im)(2)(H2O)(2)] (1)-Compound 1 was characterised by elemental analysis, IR and electronic spectra, and thermogravimetric analysis both in air and argon. It is interesting to find that ESR spectraof 1 both at 300K and 77K gave g values characteristic of an axially compressed octahedral geometry (g(perpendicular to) > g(11) > 2.00), around Cu(II) centre in the heteronuclear complex both in solution and solid phase. It is worth mentioning that the corresponding copper(II)-zinc(II) heteronuclear complex of 1 was reported to exhibit an axiallyelongated octahedral geometry around Cu(II) centre with g(11) > g(perpendicular to) > 2.00 values.
