Soft template synthesis in the cobalt(III)–1,2-diaminoethane-1,2-dithione–propanone triple system on a K[CoFe(CN)6]-gelatin-immobilized matrix

Abstract

Complexation of Co III , in the form of K[CoFe(CN) 6 ]-gelatin-immobilized matrix, in contact with aqueous-alkaline solutions (pH * 12) containing 1,2-diaminoethane-1,2-dithione and propanone, has been studied. Template synthesis leading to a chelate Co III coordination compound with a tetradentate N,N,S,S-donor ligand identified as 4,4,6-trimethyl-1,9-diamino-1,9-dimercapto-3,7-diazanon-3-en-2,8-dithione and hydroxy co-ligand occurs under these specific conditions. 1,2-Diaminoethane-1,2-dithione and propanone are the ligand synthons in this process.

“…In KFe[Fe(CN) 6 ] and KCo[Fe(CN) 6 ] GIM , the processes of self-assembly ( 3 .8) are implemented. On the one hand, they are reminiscent of the general processes of ( 3 .4), and on the other hand, they are reminiscent of the general processes ( 3 .6); therefore, similar [M L3 (H 2 O)(OH)] (M=Fe, Co) complexes are formed ( 62 , 63 ).…”
