Abstract. Treatment of the hydrazine salt [Ru(COD)(H2NNH2)4][BPh4]2 with excess of P(OMe)2Ph in acetone gave a homoleptic complex trans-[Ru{P(OMe)2Ph}6][BPh4]2, which was characterized by IR, 31P{1H}, 13C{1H}, and 1H NMR spectroscopy, elemental analysis, and X-ray crystallography. The ruthenium in the complex has distorted octahedral coordination arrangement and bonded to all the six P(OMe)2Ph molecules through the phosphorus atoms.
