Abstract :
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 R22(16)] which are linked into chains extending along a. Further C—H⋯O hydrogen bonding extends the structure along b through cyclic R22(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.
