The title compound, C(19)H(13)ClF(2)N(2)O(3), was prepared by the reaction of (Z)-ethyl 3-amino-3-(4-chloro-phen-yl)-2-cyano-acrylate and 2,6-difluoro-benzoyl chloride. The dihedral angle between the chloro-benzene and fluoro-benzene rings is 37.0 (1)°. The ethyl group is disordered over two positions [occupancies = 0.52 (2):0.48 (2)]. In addition to intra-molecular N-H⋯O and N-H⋯F hydrogen bonds, the crystal packing shows the mol-ecules to be connected by inter-molecular C-H⋯O and C-H⋯N hydrogen bonds.
标题化合物C(19)H(13)ClF(2)N(2)O(3)是由(Z)-3-氨基-3-(4-氯苯基)-2-氰基丙烯酸乙酯与2,6-二氟苯甲酰氯反应制备而成。氯苯环和氟苯环之间的二面角为37.0 (1)°。乙基在两个位置上无序分布[占有率 = 0.52 (2):0.48 (2)]。除了分子内的N-H⋯O和N-H⋯F氢键外，晶体堆积还显示分子通过分子间的C-H⋯O和C-H⋯N氢键相连。
