4,6-Dinitro-pyrogallol.


ABSTRACT: In the title mol-ecule, C(6)H(4)N(2)O(7), the two nitro groups are tilted with respect to the aromatic ring by 11.2?(1) and 10.9?(1)°. All three hy-droxy groups are involved in the formation of bifurcated intra- and inter-molecular O-H?O hydrogen bonds. The crystal packing exhibits short O?O distances of 2.823?(2)?Å between two O atoms of the nitro groups.
