The arene-ruthenium complex [Ru(η6-C10H 14)(dppf)Cl]PF6 (1) was used as a precursor for the syntheses of the [Ru(η6-C10H14)(dppf)Br] PF6 (2), [Ru(η6-C10H14)(dppf)I] PF6 (3), [Ru(η6-C10H14)(dppf) SnF3]PF6 (4) and [Ru(η6-C 10H14)(dppf)Cl][SnCl3]·0.45CH 2Cl2 (5) complexes by its reactions with KBr, KI, SnF 2 and SnCl2, respectively. All of the compounds were characterized by NMR, IR, 57Fe and 119Sn-Mo?ssbauer spectroscopy, and cyclic voltammetry. The single-crystal X-ray structure analysis of the [Ru(η6-C10H14)(dppf)Cl] [SnCl3]·0.45CH2Cl2 complex revealed the expected piano-stool geometry. Cyclic voltammograms of the complexes showed only one quasi-reversible electrochemical process, involving the oxidation of Fe(II) and Ru(II) at the same potential, which was confirmed by exhaustive electrolysis experiments. 57Fe-Mo?ssbauer parameters obtained for the complexes (1-5) were fitted with one doublet corresponding to a site of one iron(II). The 119Sn-Mo?ssbauer parameters of the complex (4) indicate that tin is tetra covalent.
