The title acid, C19H16O2, crystallized in space group P
. In this structure, a hydrogen bond of the `cyclic dimer ' type is formed about a center of symmetry. The Odonor
Oacceptor distance is 2.647 (1) Å. The carboxylic H and O atoms are ordered. The dihedral angle between the best-fit naphthalene plane and the carboxylic group plane is 11.1 (2) °.
