摘要：
The maximum deviation from the mean plane of the furobenzopyranone skeleton of the title compound, C13H9NO5, indicates a reasonably planar system. The other non-H atoms are nearly coplanar with this three-ring framework. Intra- and intermolecular C-H . . . O hydrogen bonds are observed. The crystal packing is determined by such contacts and the molecules are stacked in sheets with a spacing of 3.47 Angstrom.
