2-Amino-4-nitro­phenol–1-(2,4,6-trihy­droxy­phen­yl)ethanone (1/1)

In the title compound, C(6)H(6)N(2)O(3)·C(8)H(8)O(4), 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.
