In the title compound, C15H10ClNO3, a substituted chalcone, the dihedral angle between the benzene rings is 5.1 (7)°. The nitro group makes a dihedral angle of 12.5 (3)° with the benzene ring to which it is attached. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into a one-dimensional array along [010]. The crystal studied was an inversion twin, with a refined ratio for the twin components of 0.6060 (9):0.3939 (1).
在标题化合物C₁₅H₁₀ClNO₃(一种取代查尔酮)中,苯环之间的二面角为5.1 (7)°。硝基与其相连的苯环形成的二面角为12.5 (3)°。在晶体中,弱的C—H⋯O相互作用将分子沿[010]连接成一维阵列。所研究的晶体是一个倒易孪晶,孪晶组分的精修比例为0.6060 (9):0.3939 (1)。
