Abstract
The molecule of the title compound, C(13)H(9)N(3)O, is achiral but forms a chiral arrangement in the crystal structure. The mol-ecule adopts an E configuration with respect to the N=N bond and is almost planar, with an r.m.s. deviation of 0.0439 Å from the plane through all atoms in the mol-ecule. The dihedral angle between the two benzene rings is 2.2 (2)°. In the crystal structure, inter-molecular O-H⋯N hydrogen bonding generates a chain.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. |
