Template Synthesis in the Cu(II)-Dihydrazinomethanethione-Acetone Ternary System

摘要

Complex formation in the Cu(II)-dihydrazinomethanethione(H2NHN-CS-NHNH2)-acetone ternary system in an ethanol solution containing CuCl2,dihydrazinomethanethione,and acetone,as well as on contact of gelatin-immobilized copper(II)hecacyanoferrate(II)with alkaline(pH >10)aqueous solutions containing the above organic compounds was studied.It was found that template synthesis is realized in both cases but gives different products:in the first case,a heteroligand chelate of CuL~1(OH)with 9-hydrazino-9-mercapto-4,6,6-trimethyl-2,3,7,8-tetraazanona-3,8-dienethiohydrazide and hydroxide ion is formed,while in the second,a chelate of CuL~2 with 2,8,10,10,16-pentamethyl-3,4,6,7,11,12,14,15-octaazaheptadeca-2,5,7,12,15-pentaene-5,13-dithiol.In both cases,dihydrazinomethanethione and acetone function as ligsons.A scheme of involved processes is suggested.
