The characterization data are consistent with a cis arrangement for the dppe ligands and a bidentate coordination of the propionate ligand through carboxylate oxygens. Cytotoxicity assays were carried out on human and murine cancer and normal cell lines. In general, the [Ru(eta(2)-O2CCH2CH3)(dPPe)(2)]PF6 complex was more cytotoxic than both its precursor cis-[RuCl2(dppe)(2)] and the reference metallodrug cisplatin. The best results against the HepG2 human tumour cell line and S180 murine tumour cell line were found with IC50 values of 6.5 +/- 0.2 and 0.18 +/- 0.03 mu M respectively.
