In the title compound, [Mo(C5H5)(CO)2(C3H9P)2]CF3SO3, the cationic complex displays a classical four-legged piano-stool square-pyramidal geometry with a trans configuration of the basal ligands around the Mo atom. The cyclopentadienyl (Cp) ligand occupies the apical position of the piano-stool configuration. The average Mo—P bond length of the two trans PMe3 ligands is 2.474 (5) Å and the Mo—Cp centroid distance is 2.003 (2) Å.

To a dark purple solution of 0.85 g (2.15 mmol) of [CpMo(CO)3][SO3CF3] (Markham et al., 1985) in dichloromethane was added 1 ml (0.735 g, 9.66 mmol) of PMe3 at room temperature. The reaction was stirred overnight. The resulting yellow solution was transferred to an ether–hexane mixture (10: 1), cooled to -78°C. A yellow solid precipitate resulted. Room temperature recrystallization from hexane–dichloromethane afforded yellow crystals of (I) suitable for X-ray analysis.
All H atoms attached to C atoms were fixed geometrically and treated as riding with C—H = 0.98 Å (methyl) and 0.95 Å (Cp) with Uiso(H) = 1.2Ueq(Cp) or Uiso(H) = 1.5Ueq(methyl).

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. |

The title compound was prepared as part of our ongoing study on mixed ligand complexes (Changamu et al., 2006). It crystallizes in a monoclinic P21/n space group having a square-pyramidal geometry of ligands around Mo typical of four-legged piano-stool CpMoL4 complexes (Kubáček et al., 1982; Fettinger et al.,1998). The complex shows a trans orientation of the two phosphine ligands.
A cation-anion paired complex [Mo(C5H5)(CO)2(PMe3)2][Mo(C5H5)(CO)3] also having a similar arrangement of ligands around the cationic moiety has been previously reported (Schubert et al., 1982).
The title compound forms an adduct pair with trifluorosulphonic acid (trifluoromethanesulfonate) group. Generally these complexes may be considered as disubstituted derivatives of [CpMo(CO)4]+ in which double CO-substitution leads to either a cis or a trans product (Treichel et al.,1967; Haines et al., 1967). However, due to unfavourable steric interactions between bulky ligands only the trans isomer was observed in the title complex. The influence of steric size on the spatial orientation of the ligands is further evidenced by the large difference in the angles between the dissimilar trans ligands. Hence the P12—Mo1—P13 bonds angle is 130.34 (4)° while the C16—Mo1—C17 bonds angle is only 110.75 (4)°. The crystal of (I) is stabilized by a series of short inter-molecular contacts between neighbouring molecules.
