Crystal structure of N-(2-hydroxyethyl)-5-nitroisophthalamic acid monohydrate

In the title compound, C10H10N2O6 center dot H2O, the carboxylic acid group and the nitro group are essentially coplanar with the benzene ring [maximum deviation = 0.0264 (9) angstrom], while the amide group is oriented at a dihedral angle of 9.22 (5)degrees with respect to the benzene ring. In the crystal, classical O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds and weak C-H center dot center dot center dot O interactions link the organic molecules and water molecules of crystallization into a three-dimensional supramolecular architecture.
