2-(4-Chlorobenzoyl) benzoic acid

Abstract

Crystals of the title compound, C14H9ClO3, are stabilized by O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds and C-H center dot center dot center dot pi interactions. O-H center dot center dot center dot O hydrogen bonds generate centrosymmetric dimers. O-H center dot center dot center dot O and two C-H center dot center dot center dot O hydrogen bonds generate spirocyclic 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 center dot center dot center dot pi interactions. The dihedral angle between the aromatic rings is 88.07 (11)degrees.
