Synthesis and characterization of mixed-ligand Zn(II) and Cu(II) complexes including polyamines and dicyanodithiolate: in vitro cytotoxic activity of Cu(II) compounds

Potentially bi-, tri- and tetra-dentate polyamines (1,3-diaminopropane (pn); diethylenetriamine (tren), tris(2-aminoethyl)amine (tetraen)) react with divalent zinc and copper nitrate salts in the presence of the 1,1-dicyano-2,2-ethylenedithiolate dipotassium salt (K2-mnt) to afford a variety of compounds in which the dithiolate acts as counter dianion or participates directly in metal coordination...
