Description
Summary: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].
