Binuclear transition metal complexes of bicompartmental SNONS donors were synthesized and characterized by various physico-chemical techniques. Two different precursors with chloromethyl/formyl functionality at the 2 and 6 positions of phenolate ring are used to construct the ligands. The quinoxaline scaffolds provide SN donors incorporated at the 2 and 6 positions. Copper and zinc complexes are square pyramidal, whereas nickel and cobalt complexes are octahedral. The influence of two metal centers in terms of cooperative effect on the electronic, magnetic, electrochemical, and structural properties was investigated.

Ligands derived from quinoxaline-2,3-(1,4H)-dithione are treated with Co(II), Ni(II), Cu(II), and Zn(II) chlorides to yield stable complexes. The prepared compounds are characterized by spectro-analytical techniques and magnetic susceptibility measurements, and the coordination behavior of ligands is discussed. All the complexes are octahedral and mononuclear with general formula [MLCl2(H2O)]. The electrochemical behavior of the synthesized compounds was investigated by cyclic voltammetry studies and the redox activity is explained.
