In the title chalcone derivative, C(15)H(9)Cl(3)O, the dihedral angle between the 2-chloro-phenyl and 2,4-dichloro-phenyl rings is 41.79 (14)°. Weak C-H⋯O and C-H⋯Cl intra-molecular inter-actions involving the enone unit generate S(5) ring motifs. In the crystal structure, the mol-ecules are arranged in a head-to-tail manner along the a axis. These chains are stacked along the b axis.
在标题查尔酮衍生物C(15)H(9)Cl(3)O中,2-氯苯基与2,4-二氯苯基环之间的二面角为41.79 (14)°。涉及烯酮单元的弱C-H⋯O和C-H⋯Cl分子内相互作用产生S(5)环基序。在晶体结构中,分子沿a轴以头对尾的方式排列。这些链沿b轴堆积。
