SOME COMPLEXES OF COPPER(II) WITH N,n-Disubstituted DITHIOOXAMIDES DERIVED FROM Α-Aminoacids AND Α-Aminoacid ESTERS

Abstract

The binuclear copper(II) complexes Cu2(L-4H)(H2O)2 (L = N,N -bis (carboxymethyl) dithiooxamide -GlyDTO and N,N-bis(1-carboxyethyl) dithiooxamide -AlaDTO) and Cu2(L-2H)Cl2 (L =methyl or ethyl ester of L) were synthesized. The structure of the complexes was studied employing IR, electronic, and ESR spectroscopy and conductivity measurements. The IR data indicate that the ligands act as bistridentates, with N, S, 0 -coordination to the copper(II) ion.
