【Abstract】 A number of coordination compounds having general formula M₁or₂ [Mo₂O₄（C₂O₄）₂]. nH₂O （where M=divalent or univalent metals） were prepared and their thermal stabilies in the solid state were studied with gas chromatographic method in a helium and a hydrogen atmosphere. The results indicated that the products are H₂O, CO and CO₂ in both atmospheres, but in case of Ni and Cd salts a smaller amour of CH₄ were produced in Hydrogen atmosphere. The sources of H₂O formed arised from 3 parts: crystallized, coordinated and reduced. The temperature of losing crystallized H₂O of coordinating salts is lower than that of their decomposition, and the temperature of losing coodihating H₂O was in the range of starting decomposition of coordinating salts. The reduced water was formed only in hydrogen atmosphere. From gas chromatographic diagrams, the thermal decomposition of complexes had 2 temperature ranges, in the lower one, Co and CO₂ appeared with the quantity of the latter bigger than that of the former in peak area, while in the higher one, there appeared only CO except in Ba salts in a He atmosphere and in Ba and Cd salts in a H₂ atmosphere. The results from gas chromatography indicated that the thermal stability of complexes decreases approximately with the increase in the ionic potential of the central metal ion.更多还原
