Abstract:
The title acid, C19H16O2, crystallized in space group P1. In this structure, a hydrogen bond of the 'cyclic dimer' type is formed about a center of symmetry. The O(donor)...O(acceptor) distance is 2.647 (1) A. The carboxylic H and O atoms are ordered. The dihedral angle between the best-fit naphthalene plane and the carboxylic acid group plane is 11.1 (2) degrees.
