Hydroxy Complexes of Platinum(II) and Palladium(II)

Abstract

The preparation of hydroxy bridged complexes, [M2(OH)2L4][BF4]2, where M = Pt and L = triethylphosphine, triphenylphosphine or pyridine, or where M = Pd and L = triphenylphosphine, is described. The structures are unambiguously established by infrared, nuclear magnetic resonance, and X-ray crystallographic studies. The complexes are surprisingly stable, and in particular, resist bridge cleavage by tertiary phosphines under conditions which easily cleave analogous chloro bridged complexes.
