Abstract

The complex [Zn(Phen)(H2O)L2] (I), where HL is 5-benzyltetrazole, Phen is 1,10-phenanthroline,
was synthesized. The compound was characterized by standard physicochemical methods (elemental
analysis, powder X-ray diffraction, IR spectroscopy). According to X-ray diffraction data (CCDC no.
2220597), zinc coordination environment in the crystal structure of I corresponds to a distorted trigonal
bipyramid. The ligand HL is monodentate and is coordinated via tetrazolate ring nitrogen. The stability of
complex I was studied by NMR spectroscopy in DMSO. The cytotoxic properties of the compound were
assessed against HepG-2 (hepatocellular carcinoma) and MRC-5 (noncancerous human fibroblasts) cells.
Complex I exhibits weak cytotoxic properties in the studied concentration range (1–100 μM).

Keywords
