Preparation, characterisation and biological activity of some metal complexes derived from new dithiocarbamate of heterocyclic ligand

Abstract

In this study, synthesised new ligand: potassium 2,2'-(quinoxaline-2,3-diyl)bis(1-phenylhydrazinecarbodithioate) (L). The ligand synthesised by reacting N¹,N²-dip-tolyloxalamide as the starting material with CS₂ and KOH to add the CS₂ group and then with phenylendiammine to achieve (L).

The ligand used in the synthesis of complexes with (Co^II, Ni^II and Cd^II). The new ligand and its complexes characterised by FT-IR, UV-Vis, ¹H, ¹³C-NMR, Mass spectroscopy, and elemental analysis, in addition to the above techniques were using magnetic moment, atomic absorption, chloride content, and melting point to describe the metal complexes.
