A solution of 0.49 g of C5HPh3PPh2CH3 and 1.06 g of Mo(CO)3(CH3CN)3 in 20 ml of THF was refluxed under argon for 3 h, during which time the solution developed a black-green color. The reaction mixture was cooled and filtered, and the solid residue was washed with THF. The resulting filtrate was then treated with 200 ml of hexane to precipitate a yellow solid that was collected and washed with hexanes. The solid was dried in vacuo to yield 0.40 g yellow product. X-ray quality crystals were obtained by re-crystallization from CH2Cl2 solution at 243 K by layering with hexane.
C-bound H atoms were placed in calculated positions (C—H = 0.93 Å) and refined in the riding-model approximation with Uiso(H) = 1.2Ueq(C).
Coordination complexes of phosphonium cyclopentadienylides have attracted more and more attention in recent years because of their application in catalysis. Although phosphonium cyclopentadienylides were first reported in 1956 by Ramirez & Levy, only few compounds beyond C5H4PPh3 have been reported, probably due to the difficulties in characterizing them (Brownie et al., 2007). It is supposed that the behavior of this class of compounds depends on the substitutions on phosphorus.
The title compound, {Mo[η5-C5HPh3(PPh2CH3)](CO)3}, contains a Mo(0) atom in a typical piano stool coordination. The Mo atom is coordinated by a η5-(1,2,3,4,5-)-1-(methyldiphenylphosphonio)-2,3,5-triphenyl-2,4- cyclopentadien-1-yl ligand and three carbonyl groups. The distance between the Mo atom and the cyclopentadienyl ring is 2.0616 (13) Å. The P—C1 bond length, i.e. the phosphonium cyclopentadienylide bond, is 1.779 (2) Å, which lies between that of a typical P—C single bond (1.870 Å; Weast, 1984) and a P═C double bond (1.660 Å; Bart, 1969). This behavioutr consistent with the zwitterionic resonance structure of such phosphonium cyclopentadienylide compounds.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Coordination complexes of phosphonium cyclopentadienylides have attracted more and more attention in recent years because of their application in catalysis. Although phosphonium cyclopentadienylides were first reported in 1956 by Ramirez & Levy, only few compounds beyond C5H4PPh3 have been reported, probably due to the difficulties in characterizing them (Brownie et al., 2007). It is supposed that the behavior of this class of compounds depends on the substitutions on phosphorus.
The title compound, {Mo[η5-C5HPh3(PPh2CH3)](CO)3}, contains a Mo(0) atom in a typical piano stool coordination. The Mo atom is coordinated by a η5-(1,2,3,4,5-)-1-(methyldiphenylphosphonio)-2,3,5-triphenyl-2,4- cyclopentadien-1-yl ligand and three carbonyl groups. The distance between the Mo atom and the cyclopentadienyl ring is 2.0616 (13) Å. The P—C1 bond length, i.e. the phosphonium cyclopentadienylide bond, is 1.779 (2) Å, which lies between that of a typical P—C single bond (1.870 Å; Weast, 1984) and a P═C double bond (1.660 Å; Bart, 1969). This behavioutr consistent with the zwitterionic resonance structure of such phosphonium cyclopentadienylide compounds.
