Abstract
Thiophene-2-carbaldehyde N(4)-cyclohexylthiosemicarbazone C12H17N3S2 (HL) and diorganotin(IV) complex [Ph2Sn(L)Cl] (1) have been synthesized and characterized by elemental analysis, IR, and single-crystal X-ray diffraction. Complex 1 contains mononuclear neutral molecule composed of one five-coordinated diorganotin(IV) ion, one NS bidentate anionic thiosemicarbazone ligand, one chloridion, and two phenyl group, respectively. In vitro biological studies have indicated that coupling of HL with Ph2Sn(IV) leads to an enhancement of the cytotoxicity of the free ligand. Importantly, complex 1 could distinguish the human liver hepatocellular carcinoma HepG-2 cells from normal hepatocyte QSG7701 cells.
