چکیده
The mol-ecule of the title compound, C(15)H(14)N(4)O(3), is completed by the application of crystallographic twofold symmetry, with the carbonyl group lying on the rotation axis. The mol-ecule is close to planar: the greatest deviation of a torsion angle from 0° is 7.3 (2)° about the bond linking the phenol ring to the rest of the mol-ecule. An intra-molecular O-H⋯N(imine) hydrogen bond is formed in each half of the mol-ecule. The carbonyl O atom is anti with respect to the amine H atoms and this allows for the formation of N-H⋯O(hydrox-yl) hydrogen bonds in the crystal, which results in supra-molecular layers lying parallel to (100).

The title compounds, C23H21ClN2O2, differ from each other only by the position of the Cl atom on the corresponding benzene ring: meta relative to the central sp3 C atom for (I) and para for (II). In (I), the hy-droxy-phenyl rings are almost parallel, the dihedral angle between the mean planes being 9.2 (2)°, but in (II), the relative position of the ring is different, characterized by a dihedra...

In the title Schiff base mol-ecule, C(13)H(11)ClN(2)O, the non-H atoms are approximately coplanar (r.m.s. deviation = 0.115 Å) and the two benzene rings are twisted by 9.36 (3)° with respect to each other. The hy-droxy group is hydrogen bonded to the azomethine N atom. In the crystal, an N-H⋯π inter-action is observed between the imino group and the hy-droxy-benzene ring of an adjacent mol-ecule.
