In the racemic title compound, C24H25NO9, the dihedral angle between the planes of the two benzene-ring systems is 80.16 (6)°, while the side-chain conformation is stabilized by a methylene–carboxyl C—H...O hydrogen bond. Weak intermolecular C—H...O hydrogen bonds form inversion dimers [graph setR22(16)] which are linked into chains extending alonga. Further C—H...O hydrogen bonding extends the structure alongbthrough cyclicR22(10) motifs. Although no π–π aromatic ring interactions are present in the structure, C—H...π ring interactions acrosscgenerate an overall three-dimensional supramolecular structure.
