2-(2-Fluorobenzoylmethyl)benzoic acid

In the title compound, C15H11FO3, the aromatic rings are oriented at a dihedral angle of 69.26 (3)°. In the crystal structure, inversion dimers arise from pairs of intermolecular O—H⋯O hydrogen bonds, and C—H⋯O hydrogen bonds further consolidate the packing. There are also C—H⋯π contacts between the benzoic acid and 2-fluorobenzene rings.

In the crystal structure, inversion dimers arise from pairs of intermolecular O-HÁ Á ÁO hydrogen bonds, and C-HÁ Á ÁO hydrogen bonds further consolidate the packing. There are also C-HÁ Á Á contacts between the benzoic acid and 2-fluorobenzene rings.

Supplementary data and figures for this paper are available from the IUCr electronic archives (Reference: HK2566).  (Hill, 1986;Napolitano, 1997).
In the crystal structure, intermolecular O-H···O and C-H···O hydrogen bonds (Table 1) link the molecules (Fig. 2), in which they may be effective in the stabilization of the structure. There also exist C-H···π contacts (Table 1) between the benzoic acid and 2-fluorobenzene rings.

Refinement
H atoms were positioned geometrically, with O-H = 0.82 Å (for OH) and C-H = 0.93 and 0.97 Å for aromatic and methylene H, respectively, and constrained to ride on their parent atoms with U iso (H) = 1.2U eq (C,O).
