摘要：

Complexation processes in a cobalt(II) hexacyanoferrate(II) gelatin-immobilized matrix under the action of aqueous solutions containing dithiooxamide H2N−C(S)−C(S)−NH2 and glyoxal HOC−CHO at pH>10 were studied. Under these conditions, mild template synthesis occurs to form a CoIII chelate with the (N,N,S,S)-ligand,viz. 2,7-dithio-3,6-diazaoctadiene-3,5-dithioamide-1,8, with a metal to ligand ratio of 1∶1, where dithiooxamide and glyoxal act as ligand synthons. The reaction mechanism is discussed.
