2,2′-(4,6-Dinitro-1,3-phenylenedioxy)diacetic acid dihydrate

Abstract

In the title compound, C10H8N2O10·2H2O, the skeleton of the dicarboxylic acid molecule is approximately planar, the largest deviation being 0.477 (1) Å for an O atom of a nitro group; this nitro group is twisted out of the plane of the ring by 24.6 (1)°. Adjacent molecules are linked by O—H...O hydrogen bonds, which connect the dicarboxylic acid and water molecules into a three-dimensional supramolecular network.
