RESUMEN
The crystal structure of the title compound, C19H15O2P, features pairs of mol-ecules joined by O-Hâ¯O hydrogen bonds across crystallographic inversion centers. In addition, π-π inter-actions, with a centroid-centroid distance of 3.6273â (9)â Å between the fluorene ring systems, connect the dimers into chains along [01-1]. The three rings make dihedral angles of 1.34â (9), 1.52â (10) and 1.51â (7)° with each other.
RESUMEN
The crystal structure of the title compound, C(7)H(9)O(2)P, displays O-Hâ¯O hydrogen bonding , which links individual mol-ecules related via the c-glide plane and translational symmetry along the crystallographic b-axis direction into continuous chains.
RESUMEN
The title compound, C(13)H(13)O(2)P, crystallized as enanti-omerically pure crystals; for the crystal measured, the P atom has R stereochemistry. The crystal structure displays O-Hâ¯O hydrogen bonding, which links individual mol-ecules related by a 2(1) screw axis parallel to the crystallographic a-axis direction into continuous chains.
