Abstract

Two kinds of heterometal coordination polymer precursors, {Sm[M(ox)3]·nH2O}x (M = Fe and Co), were prepared by the reaction of K3[M(ox)3]·3H2O with Sm(NO3)3·nH2O in methanol solvent. These compounds were found to have oxalato-bridged network structure. On the other hand, the desired heterometal coordination polymer precursors could not be obtained by the present preparation method using water solvent. The thermal decomposition behaviors of these d-f heterometal coordination polymer precursors were investigated under air atmosphere. The perovskite-type oxides, SmMO3 (M = Fe and Co), were found to form in the temperature range of >600°C. The specific surface area of SmFeO3 powder increased with decreasing calcination temperature of Fe-containing heterometal coordination polymer precursor.
