Abstract
In the title salt solvate, C24H32O2P+·Br−·CHCl3, the P atom has a distorted tetrahedral geometry, and the planes of the phenyl rings form a dihedral angle of 71.86 (14)° with one another. The bromide anion is disordered and was modelled over three positions (occupancy ratio 0.50:0.35:0.15). The crystal also contains one disordered chloroform solvent molecule that was modeled over three positions (occupancy ratio 0.50:0.35:0.15). Weak intermolecular interactions (C—H⋯Br and C—H⋯O) exist between the complex cation and the bromide anion fragments. The resulting supramolecular structure is an oval-shaped arrangement of phosphonium salt molecules that surround the disordered bromide anion.
