Face-capping ruthenium complexes of several tris(2-pyridyl)phosphine (PPy3) derivatives have been examined for their potential as water oxidation catalysts. The complexes are attained by the direct substitution of PPy3 into [Ru(η-C6H6)Cl2]2 or through using an appropriate ruthenium solvate (acetonitrile or dimethyl sulfoxide). Complexes of several pyridyl substituted tris(2-pyridyl)phosphines (e.g. 4-Methylpyridyl) and associated oxide, sulfide, or selenide derivatives were prepared. The isolated products were characterized using UV-visible, fluorescence, and 1H and 31P NMR spectroscopies. Electrocatalytic activity was determined using cyclic voltammetry.
