In the title compound, CHNO, the three substituents vary in the degree of lack of planarity with the central phenyl ring. The meth-oxy group is nearest to being coplanar, with a C-C-O-C torsion angle of 6.1 (5)°. The nitro group is less coplanar, with a 12.8 (5)° twist about the C-N bond and the acetamido group is considerably less coplanar with the central ring, having a 25.4 (5)° twist about the C-N bond to the ring. The NH group forms an intra-molecular N-H⋯O hydrogen bond to a nitro-group O atom.
在标题化合物CHNO中，三个取代基与中心苯环的平面度缺失程度各不相同。甲氧基最接近共平面，C-C-O-C扭转角为6.1 (5)°。硝基的共平面性较差，C-N键的扭转角为12.8 (5)°，而乙酰胺基与中心环的共平面性明显更差，与环的C-N键扭转角为25.4 (5)°。NH基团与硝基的一个O原子形成分子内N-H⋯O氢键。
