BEHAVIOR OF MoO2Cl2·H2O ON HEATING

Abstract In an argon stream, MoO2Cl2·H2O decomposes above 80°C to HMo9O27Cl and HCl. The HMo9O27Cl formed decomposes above 205°C to a molybdenum oxide showing a hitherto unknown X-ray diffraction pattern and HCl. The decomposition is accompanied by the sublimation of MoO2Cl2·H2O. In an HCl stream, MoO2Cl2·H2O sublimes at 50–100°C. The sublimation is accompanied by the decomposition above 150°C.
