  摘要：

  Thermolysis of [(Mo(CO)(4)(mu-DPFB))(2)] (DPFB=1,4-bis(diphenylphosphino)-2,5-difluorobenzene) in acetonitrile followed by addition of triphenylphosphine yields trans-[Mo(CO)(4)(PPh(3))(2)] and free DPFB which co-crystallise. Crystal data: triclinic, space group , a=9.4976(20), b=10.0708(21), c=16.1178(29) Angstrom, alpha=100.333(16), beta=101.741(15), gamma=94.445(17)degrees, V=1474.48 Angstrom(3), Z=1. Only half of each molecule is unique, being related to the second by the inversion centre. In trans-[Mo(CO)(4)(PPh(3))(2)], little deviation from ideal octahedral geometry is seen and the Mo-P bond length of 2.500(1) Angstrom is significantly shorter than those found in the cis isomer (F.A. Cotton, D.J. Darensbourg, 5. Klein and B.W.S. Kolthammer, Inorg. Chem., 21 (1982) 294).
