N1 - In xanthene-9-carboxylic acid, CHO, hydrogen bonding is of the cyclic dimer type but involves two crystallographically inequivalent molecules and does not occur about a center of symmetry. The carboxylic H atoms are ordered. The dihedral angle (fold angle) of the xanthene core is 14.2 (1)° for molecule A and 11.3 (2)° for molecule B.

N2 - In xanthene-9-carboxylic acid, C 14 H 10 O 3 , hydrogen bonding is of the cyclic dimer type but involves two crystallographically inequivalent molecules and does not occur about a center of symmetry. The carboxylic H atoms are ordered. The dihedral angle (fold angle) of the xanthene core is 14.2 (1)° for molecule A and 11.3 (2)° for molecule B . The planes of the carboxyl groups are almost perpendicular to the xanthene cores.
