title: 2-[2-(4-Bromo-phen-yl)hydrazinyl-idene]-1,3-diphenyl-propane-1,3-dione.
abstract: The conformation of the title mol-ecule, C(21)H(15)BrN(2)O(2), is stabilized by a weak intra-molecular C-H⋯N hydrogen bond and a strong resonance-assisted N-H⋯O intra-molecular hydrogen bond. In the crystal, the mol-ecules are linked by weak inter-molecular C-H⋯O inter-actions, forming zigzag chains along the b axis.
