A series of mono- and dinuclear (eta(6)-arene) ruthenium(II) complexes were prepared by reaction of thiosemicarbazone ligands derived from benzaldehyde and ruthenium(II) precursors of the general formula [Ru(eta(6)-arene)(mu-Cl)Cl](2), where arene = p-(PrC6H4Me)-Pr-i or C6H5C3H6COOH. These complexes were characterized by NMR and IR spectroscopy, ESI-mass spectrometry and elemental analysis. The molecular structure of the mononuclear p-cymene complex was determined by X-ray diffraction analysis, revealing a pseudo-tetrahedral piano stool conformation and a bidentate N,S coordination mode of the thiosemicarbazone ligand. The complexes and ligands were evaluated for their in vitro cytotoxicity against the WHCO1 oesophageal cancer cell line. (C) 2011 Elsevier B.V. All rights reserved.
