چکیده
The asymmetric unit of the title compound, C(6)H(4)ClNO(3), contains two independent mol-ecules in which the dihedral angles between the benzene ring and the nitro groups are 2.5 (1) and 8.5 (1)°. Intra-molecular O-H⋯O hydrogen bonds involving the hy-droxy and nitro substituents result in the formation of S(6) six-membered rings. In the crystal, O-H⋯O, O-H⋯Cl and C-H⋯O hydrogen bonds together with Cl⋯O contacts [3.238 (3) and 3.207 (3) Å] generate a three-dimensional network.
