1,2-Bis(diphenyl­phosphino)-1,2-dicarba-closo-dodeca­borane

The title compound, C₂₆H₃₀B₁₀P₂, was synthesized by the reaction of 1,2-dilithio­carborane with diphenyl­choro­phos­phine in diethyl ether. The mol­ecular symmetry of the mol­ecule deviates from C_2v because of the different mutual orientations of the phenyl groups. The two P atoms of the -PPh₂ groups and two cage C atoms are almost coplanar, with a P-C-C-P torsion angle of 10.6 (3)°.

Special details

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.
