Abstract

In this study, binuclear complexes with the general formula [M2LCl4] were prepared, which were derived from salsaldehyde with 3,3′-Dimethyl-[1,1′-biphenyl]-4,4′-diamine (toluidine) and metal ions M= Co (II), Cu (II), Cd (II), and Pt (II) in a ratio (2:1) (metal: ligand). These complexes were characterized by elemental analysis (CHN), UV-Visible, FT-IR, 1H-NMR, and magnetic susceptibility, scanning electron microscopy (SEM), and molar conductivity. All complexes are non-electrolytic as the measurements confirmed that the complexes have a square planar structure. SEM showed that the complexes were of nanometric structure. The biological activity of the prepared complexes was tested to inhibit the growth of three types of bacteria: Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus.
