Crystal structure of 2-(di­phenyl­phos­phanyl)phenyl 4-(hy­droxy­meth­yl)benzoate

The title compound, C₂₆H₂₁O₃P, was obtained as by-product due to the hydrolysis of the desired tosyl­ated compound. The dihedral angles between the three aromatic rings attached to the P atom lie in the range 78.1 (1)–87.6 (1)°. The hy­droxy­methyl group is disordered between two conformations in a 0.719 (9):0.281 (9) ratio. The hy­droxy H atom is not involved in inter­molecular inter­actions, while the hy­droxy O atom serves as a donor for weak C—H...O hydrogen bonds, which link the mol­ecules into chains propagating in [0-11].
