Chemistry of Polynuclear Metal Complexes with Bridging Carbene or Carbyne Ligands. Part 84. Carbarorane Tungsten Platinum Complexes having a MU-CC6H3ME(2)-2,6 Ligand: Crystal Structures of (WPt(MU- CC6H3ME(2)-2,6))(CO)N-(Pet3)(MU-

摘要

The reaction between the salts in acetone at low temperature affords the dimetal compound in which the carbarborane ligand forms a B-H+Pt three center bond by employing a BH group in the pentagonalface of the cage. This product readily affords the complex (WPt(MU-CCH3Me202-6) (CO)2(Pet3)-(MU-:N5-C2B9H8ME2) as a mixture of two isomers. The structure of the major isomer has been established by the X ray diffraction.
