The thermal decomposition behavior of Ln-Co(1:1) cyano complexes and the composition of decomposition products have been examined. Decomposition of their CN-bridged structures proceeded on heating at about 300℃ in air, generating amorphous phases containing carbonate complexes. For the complexes comprising La-Nd, submicron sized particles of perovskite-type oxide were foumed (without single phase oxides Co_3O_4 and Ln_2O_3) from an amorphous phase by heating at about 620℃. For the complexes comprising Eu, Gd and Dy, a mixture of single oxides (Co_3O_4 and Ln_2O_3) and perovskite-type oxide was formed. The content of the perovskite-type oxide increased with the increase in decomposition temperature. For the complexes containing Ho and Yb the corresponding perovskite-type oxide could not be obtained even when the complex was decomposed at 1100℃.
