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).
在标题化合物C₉H₁₀BrN₃O中，腙部分和脂肪族链基本共面[最大偏差0.057 (15) Å]，且平均平面与苯环形成70.9 (6)°的二面角。晶体结构的主要特征是分子间的N-H⋯O氢键，它将分子沿a轴连接成锯齿链。这些链沿b轴进一步堆积。晶体结构具有非经典的分子间C-H⋯O相互作用。所研究的晶体为非等轴孪晶，孪晶比为0.505 (1):0.495 (1)。
