Abstract
In the title compound, C(7)H(7)NO(4)S, the nitro group is twisted by 10.2 (5) ° out of the plane of the benzene ring. Inversion-related mol-ecules are linked by non-classical C-H⋯O hydrogen bonds into dimers featuring an R(2) (2)(10) motif.Entities:

| Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
