The electrochemical redox behavior of three trinuclear Ni(II) complexes [Ni-3(abb)(3)(H2O)(3)(mu-ttc)](ClO4)(3) (1), [Ni-3(tebb)(3)(H2O)(3)(mu-ttc)](ClO4)(3).H2O (2), and [Ni-3(pmdien)(3)(mu-ttc)](ClO4)(3) (3), where abb = 1-(1H-benzimidazol-2-yl)-N-(1H-benzimidazol-2-ylmethyl)methan-amine, ttcH(3) = trithiocyanuric acid, tebb = 2-[2-[2-(1H-benzimidazol-2-yl)ethylsulfanyl]ethyl]-1H-benzimidazole, and pmdien = N,N,N ',N '',N ''-pentamethyldiethylenetriamine is reported. Cyclic voltammetry (CV) was applied for the study of the electrochemical behavior of these compounds. The results confirmed the presence of ttc and nickel in oxidation state +2 in the synthesized complexes. Moreover, the antibacterial properties and cytotoxic activity of complex 3 was investigated. All the complexes show antibacterial activity against Staphylococcus aureus and Escherichia coli to different extents. The cytotoxic activity of complex 3 and ttcNa(3) were studied on G-361, HOS, K-562, and MCF7 cancer cell lines. It was found out that complex 3 possesses the cytotoxic activity against the tested cell lines, whereas ttcNa(3) did not show any cytotoxic activity.
