چکیده

The molecular conformation of the title compound, C(25)H(15)NO(8), is stabilized by strong intramolecular O-H⋯O hydrogen bonds, resulting in the formation of S(1) (1)(7) ring motifs. In the crystal, π-π stacking inter-actions are observed between adjacent nitrobenzene and pyranone rings with a centroid-centroid distance of 3.513 (12) Å. The dihedral angles between the nitrobenzene ring and the coumarin ring systems are 65.61 (8) and 66.11 (8)° while the coumarin ring systems are inclined at 65.69 (8)°.
