Crystals of the title compound were obtained by recrystallization of a commercial sample from wet chloroform/diethylether at -35 °C.
All H-atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.93 Å, Uiso=1.2Ueq (C) for aromatic 0.98 Å, Uiso = 1.2Ueq (C) for CH and 0.96 Å, Uiso = 1.5Ueq (C) for CH3 atoms.
Crystals of the title compound (I) were grown as part of an ongoing project on halide hydrates (Butchard et al. 2006). In this case, the compound crystallized from wet chloroform/diethylether with only chloroform solvate. The stucture of (I) is shown below (Fig. 1). The asymmetric unit consists of two phosphonium cations, two bromide anions, and one chloroform solvate molecule. The unit cell is shown in Fig. 2.

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. |

Crystals of the title compound (I) were grown as part of an ongoing project on halide hydrates (Butchard et al. 2006). In this case, the compound crystallized from wet chloroform/diethylether with only chloroform solvate. The stucture of (I) is shown below (Fig. 1). The asymmetric unit consists of two phosphonium cations, two bromide anions, and one chloroform solvate molecule. The unit cell is shown in Fig. 2.
