Abstract
The mol-ecule of the title compound, C14H13N3O, adopts an E conformation with respect to the azomethine C=N bond, and is roughly planar, with an r.m.s. deviation of the non-H atoms from the least-squares plane of 0.100 (2) Å and a dihedral angle between the terminal benzene rings of 5.74 (12)°. An intramolecular N-H⋯N hydrogen bond closes an S(6) ring. In the crystal, mol-ecules are linked by the pairs of N-H⋯O hydrogen bonds into centrosymmetric dimers. Dimers related by translation along [010] form slanted stacks, the shortest C⋯C inter-molecular distance within the stack being 3.283 (3) Å. Weak C-H⋯π inter-actions link the stacks into a three-dimensional structure.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. |
