摘要：

Diphenylphosphine oxidatively adds across the Re=Re bond of Re2X4 (mu-dppm)2 (X = Cl or Br; dppm = Ph2PCH2PPh2) to afford the dirhenium(III) complexes Re2(mu-X)(mu-PPh2)HX3(mu-dppm)2. An X-ray crystal structure determination on the chloride complex shows the Re-Re bond distance to be 2.5918(7) angstrom. Oxidation of the bromide complex with NOPF6 produces salts of the unusual dirhenium(III,II) cation {Re2(mu-H) (mu-Br)[P(O)Ph2]Br2(NO)(mu-dppm)2}+ in which the Re-Re distance is 2.6273(8)angstrom.
