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)(O22−)(gly)2(Im)2(H2O)2](1)-Compound1 was characterised by elemental analysis, IR and electronic spectra, and thermogravimetric analysis both in air and argon. It is interesting to find that ESR spectra of1 both at 300 K and 77 K gaveg values characteristic of an axially compressed octahedral geometry (g⊥>g11>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 of1 was reported to exhibit an axially elongated octahedral geometry around Cu(II) centre withg11>g⊥>2.00 values.
