(9H-Fluoren-9-yl)(phen-yl)phosphinic acid.

Acta Crystallogr Sect E Struct Rep Online

Laboratório de Materiais Inorgânicos, Universidade Federal de Santa Maria, 97105-900 Santa Maria-RS, Brazil.

Published: January 2013

The crystal structure of the title compound, C19H15O2P, features pairs of mol-ecules joined by O-H⋯O hydrogen bonds across crystallographic inversion centers. In addition, π-π inter-actions, with a centroid-centroid distance of 3.6273 (9) Å between the fluorene ring systems, connect the dimers into chains along [01-1]. The three rings make dihedral angles of 1.34 (9), 1.52 (10) and 1.51 (7)° with each other.
