Crystal structure of N-(2-hy-droxy-eth-yl)-5-nitro-isophthalamic acid monohydrate.

In the title compound, C10H10N2O6·H2O, the carb-oxy-lic acid group and the nitro group are essentially coplanar with the benzene ring [maximum deviation = 0.0264 (9) Å], while the amide group is oriented at a dihedral angle of 9.22 (5)° with respect to the benzene ring. In the crystal, classical O-H⋯O and N-H⋯O hydrogen bonds and weak C-H⋯O inter-actions link the organic mol-ecules and water mol-ecules of crystallization into a three-dimensional supra-molecular architecture.
