Abstract
In the title compound, C11H11NO3, the di-hydro-furan-2,5-dione ring has a shallow envelope conformation, with one of the methyl-ene C atoms displaced by 0.216 (1) Å from the other atoms. These near-planar atoms subtend a dihedral angle of 55.88 (8)° with the benzene ring. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into [010] chains.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. |
