4-(Diphenylphosphanyl)benzoic acid

P.-H. Zhao, F.-Y. Sun and J.-J. Liu

Abstract: In the title compound, C19H15O2P, the dihedral angles between the benzoic acid ring and the phenyl rings are 75.64 (7) and 80.88 (7)°; the dihedral angle between the phenyl rings is 81.35 (7)°. In the crystal, inversion dimers linked by pairs of O-H...O hydrogen bonds generate R22(8) loops between the head-to-head carboxylic acid groups.
