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 set R2 2(16)] which are linked into chains extending along a. Further C-H. O hydrogen bonding extends the structure along b through cyclic R2 2(10) motifs. Although no π-π aromatic ring interactions are present in the structure, C-H.π ring interactions across c generate an overall three-dimensional supramolecular structure.
