A new method has been developed for the low-temperature synthesis of perovskite solids LaMO3 where M = Ni, Co, Mn, using binuclear complexes of the ligand N,N'-bis(3-carboxysalicylidene)ethylenediamine (H4fsaen). The thermal decomposition of such complexes was studied using a thermobalance. The solids that formed after thermal treatment from 400 to 1000-degrees-C were characterized by X-ray diffraction. Using this method perovskites LaNiO3, LaCoO3 and LaMnO3 have been synthesized at temperatures of ca. 500-600-degrees-C. The above procedure yields solids with specific surface areas substantially higher than those obtained from ordinary ceramic methods, such as citrate and the nitrate routes. (EN)
