Abstract
In the title mol-ecule, C(12)H(10)N(2)O(2), the benzene and pyridine rings form a dihedral angle of 5.01 (8)°. The amide group is twisted by 33.54 (7)° from the plane of the pyridine ring. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of O-H⋯N hydrogen bonds. N-H⋯O hydrogen bonds further link dimers related into chains along the b axis.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. |
