Abstract
The molecular geometry of the title compound has been determined by X-ray crystal-structure analysis from diffractometer data. The crystals are monoclinic, space-group P21/c, a= 12·238(6), b= 14·818(10), c= 21·687(10)Å, β= 121·28(3)°, Z= 4. The structure was solved by the heavy-atom method and refined by full-matrix least-squares to R 0·081 for 2283 reflections. The crystals are built of monomeric molecular units, with distorted octahedral co-ordination around the molybdenum atom. The molybdenum–ligand bond distances are: Mo–O 1·801(9), Mo–Cl (trans to O) 2·424(4), Mo–Cl (trans to P) 2·482(4), Mo–P (trans to Cl) 2·522(4), and Mo–P (trans to P) 2·580(5) and 2·553(5)Å.Keywords
