(E)-N′-(5-Bromo-2-methoxybenzylidene)-3-methoxybenzohydrazide
Abstract
In the title compound, C16H15BrN2O3, there are two independent molecules (A and B) in the asymmetric unit. The major difference between the two molecules is the dihedral angle formed by the aromatic rings [72.6 (2) and 18.8 (2)° for A and B, respectively]. The benzohydrazide groups are not planar and the molecules exist in trans configurations with respect to the methylidene units. The molecular packing is stabilized by two intermolecular N—H...O hydrogen bonds, forming chains parallel to the c axis. Only the A molecules of the asymmetric unit are held together by π–π interactions [centroid–centroid distance = 3.714 (3) Å].
