Abstract: | Summary cis-Dioxo(N-salicylidene-2-aminophenolato) (imidazole)-molybdenum(VI) complexes, [MoO2(Sap)(Im)], (Im = imidazole or its derivatives, sap = salicylidene-2-aminophenolate) are prepared by the ligand substitution of [MoO2(Sap)(EtOH)] with a unidentate imidazole ligand. All complexes are red or yellow, diamagnetic, non-electrolytes and possess an octahedral stereochemistry. The i.r. spectra shows two bands attributable tocis-MoO2 stretches in addition to the vibrations of the Schiff base ligand and the imidazole derivatives. Thermal degradation of the complexes result in successive loss of imidazole ligand followed by the Schiff base, with ultimate formation of MoO3 atca. 500 °C. |
