2-Meth-oxy-3,4-diphenyl-phenol.

The title compound, C(19)H(16)O(2), was isolated as the major product after the solid-state photochemical reaction of 2-meth-oxy-4,4-diphenyl-cyclo-hexa-2,5-dienone. The dihedral angles between the central ring and pendant benzene rings are 60.76†(6) and 51.64†(6)°. The O-C vector of the meth-oxy group is almost perpendicular to the plane of the central ring as indicated by the C-C-O-C torsion angle of 94.89†(18)°. Hydrogen-bonded dimers are formed in the crystal structure via O-H⋯O inter-actions. The data were collected at room temperature on a Bruker SMART X2S diffractometer in the automated mode and processed manually thereafter.
