The title Schiff base compound, C(15)H(14)BrNO(2), adopts an E configuration with respect to the C=N bond. The C and O atoms of the two meth-oxy substituents lie very close to the dimethoxy-phenyl ring plane [maximum deviation = 0.17 (1) Å]. The dihedral angle between the two aromatic rings is 43.69 (16)°, while the plane through the central C-C=N-C system is inclined at 10.6 (6)° to the dimethoxy-phenyl ring and 34.6 (3)° to the bromo-phenyl ring. In the crystal structure, each mol-ecule is involved in the formation of two inversion-related dimers through weak C-H⋯N and C-H⋯O inter-actions, respectively. These contacts link the mol-ecules into independent rows parallel to the b axis.
席夫碱化合物C(15)H(14)BrNO(2)相对于C=N键采取E构型。两个甲氧基取代基的C和O原子非常靠近二甲氧基苯环平面[最大偏差 = 0.17 (1) Å]。两个芳香环之间的二面角为43.69 (16)°，而通过中心C-C=N-C体系的平面相对于二甲氧基苯环倾斜10.6 (6)°，相对于溴苯环倾斜34.6 (3)°。在晶体结构中，每个分子分别通过弱C-H⋯N和C-H⋯O相互作用参与形成两个与反演相关的二聚体。这些接触将分子连接成平行于b轴的独立行。
