Abstract—The reaction of a solution of H[AuCl4] with 1,10-phenanthroline (Phen) in acetonitrile gave the complex (H2Phen)[AuCl4]Cl (I). According to X-ray diffraction data (CCDC no. 2165199), Phen exists in I as an unusual doubly protonated (cationic) form (H2Phen)2+. Binding of ionic structural units ([AuCl4]–, Cl–, and (H2Phen)2+) by D–H···Cl hydrogen bonds (D = N, C) gives rise to supramolecular 2D pseudo-polymer layers. The biological activity of I was measured for human ovarian carcinoma cells (SKOV3). Using MTT assay results, the half-maximal inhibitory concentration was calculated, demonstrating high selectivity of I to cancer cells in combination with low toxicity towards normal fibroblasts.
