2-[(2-Chlorophenyl)(hydroxy)methyl]phenol

Abstract

In the title compound, C13H11ClO2, the dihedral angle between the mean planes of the 2-chlorophenyl and phenol rings is 87.4 (9)°. The methyl hydroxy group lies nearly perpendicular to the plane of its attached benzene ring [O—C—C—C torsion angle = 84.3 (3)°]. The two hydroxy groups lie on the same side of the molecule and are in a slightly twisted gauche conformation [O—C—C—O torsion angle = 77.1 (8)°] to each other. In the crystal, O—H...O hydrogen bonds between nearby methylhydroxy groups form dimers in alternating pairs aligned diagonally along the b axis. A view along the c axis reveals a hexameric aggregate mediated by a ring of six O—H...O hydrogen bonds generating an R66(12) motif loop.
