[1,1'-Bis(diphenylphosphino)ferrocene]tetracarbonylmolybdenum

Two crystallographically independent but chemically similar molecules (A and B) form the asymmetric unit of tetracarbonyl-1 κ 4 C-bis[μ-1 κP:2(η 5 )-diphenylphosphinocyclopentadienyl]ironmolybdenum, [{(C 17 H 14 P) 2 Fe}Mo(CO) 4 ]. The [bis(diphenylphosphino)ferrocene] ligand coordinates via the two P atoms, completing the cis-octahedral coordination of molybdenum. The carbonyl ligands trans to these phosphorus donors show the expected carbon-metal bond shortening. The ferrocene ligands have slightly non-parallel cyclopentadienyl rings, with staggered arrangements, and the P atoms are significantly elevated from the planes of the cyclopentadienyl rings
