The title compound, C(10)H(12)N(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit which differ in the orientation of the meth-oxy group. Each independent mol-ecule adopts a trans configuration with respect to the C=N bond. In the crystal structure, mol-ecules are linked into chains running along [001] by N-H⋯O and N-H⋯N hydrogen bonds. In addition, an inter-molecular C-H⋯π inter-action is observed.
标题化合物C(10)H(12)N(2)O(3)在不对称单元中结晶出两个独立的分子,它们的甲氧基取向不同。每个独立分子相对于C=N键采取反式构型。在晶体结构中,分子通过N-H⋯O和N-H⋯N氢键连接成沿[001]方向延伸的链。此外,还观察到分子间的C-H⋯π相互作用。
