Crystal structure of diethyl 2-acet­oxy-2-[3-(4-nitro­phen­yl)-3-oxo-1-phenyl­prop­yl]malonate

In the racemic title compound, C(24)H(25)NO(9), 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 R (2) (2)(16)] which are linked into chains extending along a. Further C—H⋯O hydrogen bonding extends the structure along b through cyclic R (2) (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.
