Abstract
In the structure of the title compound, C(11)H(13)NO(3), the conformations of the N-H and C=O bonds in the amide fragment are trans to each other. In the crystal, mol-ecules are linked into a 2(1) helical chain that propagates along the c axis through N-H⋯O inter-actions.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. |
