The title compound, C(15)H(12)BrClN(2)O(3), was obtained by the condensation reaction between 3-bromo-5-chloro-2-hydroxy-benzaldehyde and 2-methoxy-benzohydrazide. The mol-ecule is essentially planar, with a dihedral angle between the two benzene rings of 4.7 (2)°, and displays an E configuration about the C=N double bond. The mol-ecular conformation is stabilized by intramolecular O-H⋯N and N-H⋯O hydrogen bonds. In the crystal structure, mol-ecules are linked into zigzag chains running parallel to the c axis by inter-molecular C-H⋯O hydrogen bonds. The chains are further connected through aromatic π-π stacking inter-actions with centroid-centroid distances of 3.583 (4) Å.
标题化合物C(15)H(12)BrClN(2)O(3)是通过3-溴-5-氯-2-羟基苯甲醛与2-甲氧基苯甲酰肼之间的缩合反应得到的。分子基本呈平面状，两个苯环之间的二面角为4.7 (2)°，并且C=N双键呈现E构型。分子构象通过分子内的O-H⋯N和N-H⋯O氢键得以稳定。在晶体结构中，分子通过分子间的C-H⋯O氢键连接成平行于c轴的锯齿链。这些链通过质心-质心距离为3.583 (4) Å的芳香π-π堆积相互作用进一步连接。
