N′-[(E)-1-(5-Bromo-2-hydroxyphenyl)ethylidene]-4-nitrobenzohydrazide

Abstract

The title compound, C15H12BrN3O4, displays a trans conformation with respect to the C=N double bond. The central atoms around the C=N double bond are not coplanar, in contrast to the aromatic rings, which exhibit a dihedral angle of 1.80 (4)° between their mean planes. An intramolecular O—H...N hydrogen bond occurs. In the crystal, molecules are connected via intermolecular N—H...O hydrogen bonding into chains along the a axis.
