Ortho-(1-naphthoyl)benzoic acid.
The title acid, C18H12O3, crystallized in the centrosymmetric space group C2/c and exhibits carboxyl group hydrogen bonding of the cyclic dimer type about a center of symmetry. The Odonor-Oacceptor distance in the hydrogen bond is 2.692 (2) A. In addition, seven C-H groups and the three O atoms in the molecule are involved in significantly attractive C-H...O interactions with 11 neighbors, forming a three-dimensional network. The carboxylic H atom is ordered, as are the carboxylic O atoms.
