The title compound, C(18)H(17)F(2)NO(3), consists of three individually planar subunits, namely two benzene rings and one amino-acrylate group. The amino-acrylate group forms dihedral angles of 5.92 (7) and 50.21 (6)° with the difluoro and methoxy benzene rings, respectively. The dihedral angle between the two benzene rings is 55.25 (7)°. The mol-ecules exhibit intra-molecular N-H⋯O and N-H⋯F inter-actions and form a three-dimensional network via inter-molecular C-H⋯O and C-H⋯π hydrogen bonds.
标题化合物C(18)H(17)F(2)NO(3)由三个各自平面的亚基组成,即两个苯环和一个氨基丙烯酸酯基团。氨基丙烯酸酯基团与二氟苯环和甲氧基苯环分别形成5.92 (7)°和50.21 (6)°的二面角。两个苯环之间的二面角为55.25 (7)°。分子表现出分子内N-H⋯O和N-H⋯F相互作用,并通过分子间C-H⋯O和C-H⋯π氢键形成三维网络。
