2-(4-Chlorobenzoyl) Benzoic Acid

Abstract

Crystals of the title compound, C14H9ClO3, are stabilized by O - H⋯O and C - H⋯O hydrogen bonds and C - H⋯π inter-actions. O - H⋯O hydrogen bonds generate centrosymmetric dimers. O - H⋯O and two C - H⋯O hydrogen bonds generate spiro-cyclic R 2 2(8)R 2 1(5) ring motifs. The R 2 2(8) and R 2 1(5) ring motifs are connected to each other by C(6) chains and C - H⋯π inter-actions. The dihedral angle between the aromatic rings is 88.07 (11)°. © International Union of Crystallography 2007.
