Abstract
In the crystal structure of the title compound, C(11)H(13)NO(3), the conformations of the N-H and C=O bonds in the amide segment are anti to each other, and that of the amide H atom is anti to the meta-methyl group in the benzene ring. Furthermore, the conformations of the amide oxygen and the carbonyl O atom of the acid segment are also anti to the adjacent -CH(2) groups. The C=O and O-H bonds of the acid group are syn to each other. In the crystal, the mol-ecules are packed into infinite chains through inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.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. |
