The title compound, C(10)H(9)NO(4), forms R(2) (2)(8) dimers due to inter-molecular O-H⋯O hydrogen bonding in the crystal structure. Two dimers are further linked to each other through two inter-molecular C-H⋯O hydrogen bonds, forming an R(3) (3)(7) ring motif. The nitro groups form an intra-molecular C-H⋯O hydrogen bond mimicking a five-membered ring. As a result of these hydrogen bonds, polymeric sheets are formed. The aromatic ring makes a dihedral angle of 42.84 (8)° with the carboxyl-ate gr ...[more]
