Abstract
The complexing processes in the triple cobalt(II)–dithiooxamide-formaldehyde and cobalt(II)–dithiooxamide-glyoxal systems taking place in the cobalt(II)hexacyanoferrate(II) gelatin-immobilized matrix in contact with aqueous alkaline solutions (pH ca. 12) containing (dithiooxamide + formaldehyde) and (dithiooxamide + glyoxal), have been studied. Template synthesis leading to macrocyclic coordination compounds with tetradentate N,N,S,S-donor ligands-(2,8-dithio-3,7-diaza-5-oxanonan-dithioamide-1,9) and (2,7-dithio-3,6-diazaoctadien-3,5-dithioamide-1,8) with CoII–CoIII redox-process occurs under these specific conditions where dithiooxamide, formaldehyde and glyoxal are the ligand synthons.
