A new complex with the formula [Cu(opd)2(H2O)(μ-SCN)Zn(opd)(SCN)3] (a) that opd =ortho-phenylenediamine was synthesized. The complex (a) was characterized using cyclic voltammetry (CV), spectroscopic methods (IR, UV-Vis) and SEM method. FT-IR show the thiocyanate ligand is located in the form of a bridge. The 1-2-phenylenediamine ligand is also bonded to metal ions through the non-bonding electron pairs of nitrogen atoms through bidentate ligand. The studies obtained from the UV-Vis spectrum confirm n → π* and π→π* intra-ligand transitions. The images obtained with the help of scanning electron microscope (SEM) showed that the particles have a uniform morphology. The average size diameter obtained from the Debye-Scherrer equation of nanocrystal complex (a) was approximately 73 nm. Finally, the antibacterial activity of the complex was investigated. The antibacterial activity of complex (a) against gram-negative bacteria is greater than that against gram-positive bacteria.
