(9H-Fluoren-9-yl)(phenyl)phosphinic acid

R. A. Burrow and R. M. Siqueira da Silva

Abstract: The crystal structure of the title compound, C19H15O2P, features pairs of molecules joined by O-H...O hydrogen bonds across crystallographic inversion centers. In addition, [pi]-[pi] interactions, 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.
