The heteronuclear Bi1-xLax[Fe(CN)(6)].nH(2)O complexes were synthesized and their crystal structures were investigated by XRD and TGA. The crystal phase was hexagonal (n = 5) for x = 1.0, and orthorhombic (n = 4) for x = 0-0.7 and their mixture (x = 0.8 and 0.9). The lattice constants for the complexes linearly increased with an increase in the x value. The single phase of the trimetallic perovskite-type Bi0.5La0.5FeO3 was obtained by its thermal decomposition at 500degreesC.
