1,4-Dihydroxy-2,3-dinitro-9,10-anthraquinone

IUCrData, 2016
In the title compound, C14H6N2O8, the anthraquinone unit is essentially planar [maximum deviation = 0.0645 (10) Å], and there are two intramolecular O–H...O hydrogen bonds forming S(6) motifs. The planes of the two nitro substituents make dihedral angles
