چکیده
The title Schiff base compound, C(15)H(15)NO(2), crystallized as the iminium-phenolate zwitterion. The H atom is localized on the imine N atom, forming a strong intra-molecular hydrogen bond with the phenolate O atom, and giving rise to an S(6) ring motif. The mol-ecule has an E conformation about the C=N bond. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains propagating along [010]. There are also C-H⋯O inter-actions present.

In the title mol-ecule, C(19)H(18)Br(4)N(2)O(2), the dihedral angle between the benzene rings is 73.9 (2)°. Two intra-molecular N-H⋯O hydrogen bonds make S(6) ring motifs. In the crystal, mol-ecules are linked via C-H⋯O inter-actions, forming chains propagating along the a-axis directon. A short C⋯Br [3.401 (5) Å] contact is present in the crystal structure, which is further stabilized by a π-π...

The title compound, C(13)H(10)N(2)O(4), crystallized as the zwitterionic tautomer. As a result, the phenolate C-O(-) bond [1.296 (2) Å] is shorter than a normal Csp(2)-O(H) bond, and the azomethine C=N bond [1.314 (2) Å] is longer than a normal C=N double bond. The mol-ecule is nearly planar, the mean plane of the nitro-substituted benzene ring forming dihedral angles of 9.83 (7) and 8.45 (9)° ...

Mol-ecules of the title compound, C(34)H(38)N(4)O(2), lie across crystallographic inversion centres. The crystal packing can be described by alternating zigzag chains along the c axis in which the molecules are linked by van der Waals interactions. There is an intra-molecular O-H⋯N hydrogen bond and the two benzene rings in the asymmetric unit make a dihedral angle of 79.81 (6)°.
