摘要：

The molecular structure of trans-W-2(CO)(6)(PPh2H)(2)(mu(2)-PPh2)(2) was determined by X-ray diffraction analysis. The two tungsten centers, bridged by two diphenylphosphido ligands, are separated by 3.0667(6) Angstrom with W-P-W angles of 77.10(5) and 77.08(5)degrees. Average tungsten-phosphorus bond distances are 2.461(17) and 2.4576(21) Angstrom for bridging and terminal phosphorus groups, respectively, with a range of 0.037 Angstrom for the former and 0.001 Angstrom for the latter. The complex crystallizes in the monoclinic space group P2(1)/c with a = 19.282( 4) Angstrom, b = 12.158( 2) Angstrom, c = 21.294( 9) Angstrom, beta = 92.821( 4)degrees, and Z = 4.
