Abstract

Binuclear platinum complexes [Pt₂(O₂)(OH)(PPh₃)₄][X] (X = ClO₄, BF₄, PF₆, or NO₃) and [Pt₂(OH)₂(PPh₃)₄][X]₂ (X = ClO₄, BF₄, or PF₆) have been prepared by the stepwise reaction of [Pt(O₂)(PPh₃)₂] with HX in CH₂Cl₂-EtOH. Their formation is accompanied by production of H₂O₂. The presence of peroxo- and hydroxo-bridges between the two platinum atoms in [Pt₂(O₂)(OH)(PPh₃)₄][ClO ₄] has been confirmed by a single-crystal X-ray analysis. The complex crystallizes in space group P1, with cell dimensions a = 14.884(3), b = 15.281 (3), c = 16.744(4) Å, α = 90.06(2), β = 108.65(2), γ = 93.11 (2)°, and Z = 2. The structure has been solved by Patterson and Fourier techniques, and refined to R 0.086 for 5 359 diffractometer data. Reaction of the peroxo-bridged species with CO yields [Pt(CO)₂(PPh₃)₂], while with SO₂ the final product contains a bidentate sulphate group.
