title: (E)-1-(4-Bromo-phen-yl)ethan-1-one semicarbazone.
abstract: In the title compound, C(9)H(10)BrN(3)O, the hydrazone portion and aliphatic chain are essentially coplanar [maximum deviation 0.057 (15) Å] and the mean plane makes a dihedral angle of 70.9 (6)° with the benzene ring. The main feature of the crystal structure is the inter-molecular N-H⋯O hydrogen bond, which links mol-ecules into zigzag chains along the a axis. These chains are further stacked along the b axis. The crystal structure features non-classical inter-molecular C-H⋯O inter-actions. The crystal studied was a nonmerohedral twin, with a twin ratio of 0.505 (1):0.495 (1).
