In the title compound, C(16)H(16)BrNO(4), the dihedral between the planes of the aromatic rings is 7.74 (18)°. The amide group is tilted with respect to the bromo- and meth-oxy-substituted aromatic rings by 36.3 (8) and 35.2 (8)°, respectively. The meta-meth-oxy groups are essentially in-plane with the aromatic ring [dihedral angles CH(3)-O-C-C = -4.6 (4) and -2.5 (4)°]. The para-meth-oxy group is markedly displaced from the ring plane [dihedral angle CH(3)-O-C-C = -72.5 (4)°]. The crystal packing is stabilized by N-H⋯O hydrogen bonds linking the mol-ecules into chains running along the b axis.
在标题化合物C₁₆H₁₆BrNO₄中,芳环平面之间的二面角为7.74 (18)°。酰胺基相对于溴代和甲氧基取代的芳环分别倾斜36.3 (8)°和35.2 (8)°。间位甲氧基基本上与芳环共面[二面角CH₃ - O - C - C = -4.6 (4)°和 -2.5 (4)°]。对位甲氧基明显偏离环平面[二面角CH₃ - O - C - C = -72.5 (4)°]。晶体堆积通过N - H⋯O氢键得以稳定,这些氢键将分子连接成沿b轴延伸的链。
