Abstract:
The title compound, C(15)H(12)BrClN(2)O(3), was obtained by the condensation reaction between 3-bromo-5-chloro-2-hydroxy-benzaldehyde and 2-methoxy-benzohydrazide. The mol-ecule is essentially planar, with a dihedral angle between the two benzene rings of 4.7 (2)°, and displays an E configuration about the C=N double bond. The mol-ecular conformation is stabilized by intramolecular O-H⋯N and N-H⋯O hydrogen bonds. In the crystal structure, mol-ecules are linked into zigzag chains running parallel to the c axis by inter-molecular C-H⋯O hydrogen bonds. The chains are further connected through aromatic π-π stacking inter-actions with centroid-centroid distances of 3.583 (4) Å.
