Abstract
In the title compound, C6H6N2O3·C8H8O4, the 2-amino-4-nitrophenol (ANP) and 1-(2,4,6-trihydroxyphenyl)ethanone (THA) molecules are both nearly planar, with r.m.s. deviations of 0.0630 and 0.0313 Å, respectively. The angle between the least-squares planes of THA and ANP is 48.99 (2)°. In THA, an intramolecular O—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds lead to the formation of a three-dimensional network. There are also intermolecular π–π interactions between the benzene rings of ANP–ANP and of THA–THA molecules, with centroid–centroid distances of 3.5313 (14) and 3.8440 (16) Å, respectively. Weak C—O⋯π and N—O⋯π interactions also occur.
