Synthesis of Co(III) molybdoheteropolyanions using carbonato-ammine Co(III) complexes as starting materials

The preparation of two cobalt(III) molybdoheteropolyanions, [CoMo6O24H6]3− and [Co2Mo10O38H4]6−, was systematically studied using some carbonato-ammine cobalt(III) complexes as starting materials. The selectivity and yields of products were significantly influenced by the number of ammine ligands and the charge on the complexes.
