2,6-Dimethyl-3-nitro-8H-furo[2,3-g][1]benzopyran-8-one

I. Wolska and J. Kossakowski

Abstract: 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-HO 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  Å.
