摘要：

The complex formation that occurs in gelatin-immobilized copper(II)hexacyanoferrate(II) matrices upon contact with aqueous alkaline (pH 12.0) solutions of 1,2-bis(thiocarbamoyl)hydrazine, H2NC(S)NHNHC(S)NH2 and 1-carbamoyl-2-(thiocarbamoyl)hydrazine, H2NC(O)NHNHC(S)NH2 has been studied. The reaction of each of these ligands with copper(II) is preceded by the destruction of copper(II)hexacyanoferrate(II) in an alkaline medium to form a polymeric copper(II) hydroxide, which is involved in the subsequent copper(II)–ligand complex formation. In both CuII–N ligand systems, two complex compounds are formed; the water-insoluble Cu2B2(H2O)2 dimer and a water-soluble product of tentative composition [CuB(HB)]− (H2B = ligand).
