The title compound, C(14)H(11)N(3)O(3), adopts an E conformation, with a dihedral angle of 41.8 (1) ° between the mean planes of the two benzene rings. One of the amino H atoms forms an intra-molecular hydrogen bond with the amide N atom, while the other H atom forms an inter-molecular hydrogen bond with the carbonyl O atom of an adjacent mol-ecule, forming dimers about inversion centers. A non-classical inter-molecular C-H⋯O hydrogen bond also links adjacent mol-ecules into dimers.
标题化合物C(14)H(11)N(3)O(3)呈E构象,两个苯环的平均平面之间的二面角为41.8 (1)°。其中一个氨基氢原子与酰胺氮原子形成分子内氢键,而另一个氢原子与相邻分子的羰基氧原子形成分子间氢键,围绕反演中心形成二聚体。一种非经典的分子间C—H⋯O氢键也将相邻分子连接成二聚体。
