N′-[(E)-(5-Bromo-2-hydroxyphenyl)(phenyl)methylidene]-4-chlorobenzohydrazide
Abstract
The Schiff base, C20H14BrClN2O2, displays a trans conformation with respect to the C=N double bond. The aromatic rings at either end of the –C(=O)–NH–N=C– fragment are nearly parallel [dihedral angle = 3.4 (5)°]. The hydroxy group forms an intramolecular hydrogen bond to the imino N atom.
