Creatinine complexes of zinc, cadmium and mercury
Abstract: Zinc, cadmium and mercury(II) complexes of creatinine of the composition M(Creat) 2 X 2 (X = Cl, Br or I) are prepared. The complexes are characterized by analytical and spectral methods. The increase in cyclic NH stretching frequency in the case of complexes (3350 cm −1 ) from that of the free ligand (3300 cm −1 ) suggested that secondary nitrogen is involved in coordination. The shift in the resonances of cyclic NH proton in the 1 H NMR and carbonyl and imine carbons in 13 C NMR when compared to the ligand indicated that cyclic nitrogen coordinates. Conductivity measurements in N, N-dimethylformamide suggested that the complexes are non-electrolytes. Thermal decomposition behaviour of the complexes is also discussed.
