[4-(Bromo­methyl)­benz­yl]triphenyl­phospho­nium bromide acetonitrile monosolvate

In the title compound, C₂₆H₂₃BrP⁺·Br⁻·C₂H₃N, the dihedral angles between the plane of the benzylic phenyl ring attached to the P atom and the planes of the three directly attached phenyl rings are 34.04 (12), 45.48 (13) and 87.18 (9)°. In the crystal, centrosymmetric pairs of cations and anions are linked into dimeric aggregates via C—H...Br hydrogen bonds. There is also a C—H...N hydrogen bond to the acetonitrile solvent mol­ecule.
