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

Abstract

In the title compound, C6H6N2O 3·C8H8O4, the 2-amino-4-nitro-phenol (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 intra-molecular 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 inter-molecular ?-? inter-actions 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?? and N - O?? inter-actions also occur. © Kocabyk et al. 2012.
