PMePh2) were determined. The two compounds are isomorphous and belong to space group Cc; unit-cell dimensions: o= 10.736 (1) A, b= 18.872 (2) A, c= 26.060 (2) Á, ß= 101.43 (1), V= 5175 (1) A3, and Z= 4 for [6c][BPh4] and o= 10.724 (2) A, b= 18.834 (2) A, c= 26.091 (3) A, ß= 101.44 (3), V= 5165 (2) A3, and Z= 4 for [7c][BPh4], The structures were refined to R= 0.045 and 0.052, respectively. The hydride ligands in [6c][BPh4] were located and refined by least squares. The geometries of the two cations are similar; the interesting difference being the metal-metal distance (W-Ir= 2.706 (1) and Mo-Ir= 2.641 (1) A). The reaction of 3 with [IrH2 (acetone) 2 (PCy3) 2]+(le), however, follows a different well-defined stoichiometrygiving 6e,[WH3-(^ S-C5H5) 2]+(11), and [IrH5 (PCy3) 2](13e).
