Abstract
The title compound, C23H25NO4, was synthesized by the reaction of 2-(4-nitrophenyl)acetonitrile and 3,5-di-tert-butyl-2-hydroxybenzaldehyde. The dihedral angle formed by the benzene ring and the mean plane through the benzopyranone ring system is 35.57 (5)°. The nitro group is almost coplanar with the attached benzene ring [dihedral angle = 5.19 (15)°]. The crystal packing is stabilized by an intermolecular C—H⋯O hydrogen-bond interaction.
