The synthesis of a new Ru-H2O complex [Ru(phen)-(H 2O)(aneS3)](ClO4)2, 2, (phen = 1,10-phenanthroline, aneS3 = 1,4,7-trithiacyclononane) is described. The complex is characterized by UV/Vis and 1-D and 2-D NMR spectroscopy in solution. The complex has been further characterized in the solid-state by X-ray diffraction analysis which displays a distorted octahedral coordination geometry around the Ru metal center. The cyclic voltammetric experiments of the complex show a pH-dependent chemically irreversible wave at Ep.a = 0.82 V, at pH = 7.0, indicating the low stability of the higher oxidation states. Nevertheless, before the complex decomposes, it is capable of electrocatalytically oxidizing benzyl alcohol (BzOH) to benzaldehyde with a second-order rate constant of 19.8 M-1s-1. © Wiley-VCH Verlag GmbH & Co.
