Preparation of [Co(TeO6H4)(en)2]+ and its condensed complexes.
Three new complexes, [Co(TeO6H4)(en)2]+,[Co(en)2(Te2O10H4)Co(en)2]2+, and [{Co(en)2}2(Te2O10){Co(en)2}2]4+ , have been isolated as their chlorides from the reaction solutions of cis-[CoCl2(en)2]+ and Te(OH)6, and their optical resolutions have been achieved.
