Abstract

The title compound, racemic bnppa, C20H13O4P, crystallizes with four mol­ecules in the asymmetric unit. Two independent centrosymmetric O—H⋯O hydrogen-bonded tetra­mers, each involving two of the symmetry-independent mol­ecules in the asymmetric unit generate the packing motif in the crystal structure. The hydro­phobic parts of the tetra­mers connect to their neighbours via C—H⋯π and π–π inter­actions [3.899 (2), 3.895 (2) and 3.803 (2) Å within the symmetric unit, 3.851 (2), 4.000 (2), 3.988 (2) and 3.905 (2) Å across centres of symmetry].
