Two P21/n monoclinic phases of fluorene-4-carboxylic acid at 296 K.

Acta Crystallogr. C 52 ( Pt 6) , 1482-6, (1996)

The structures of two phases of fluorene-4-carboxylic acid, C14H10O2, from room-temperature growths have been determined. In the alpha phase, O-H...O hydrogen bonding occurs via cyclic dimers about a center of symmetry; in the beta phase, cyclic dimers with O...
