Abstract
The title compound, C21H19BrN2O2, exists in the hydrazo tautomeric form in the crystal structure, being stablilized by an intramolecular N-H center dot center dot center dot O hydrogen bond. Aromatic pi-pi stacking helps to establish the packing [centroid-to-centroid separation = 3.6804 (14) Å].
