The mol-ecule of the title compound, C10H11N3O, is planar, including the ethyl group, as indicated by the N-C-C-C torsion angle of 1.5 (2)°. In the crystal, inversion-related mol-ecules are stacked along the a axis. Mol-ecules are oriented head-to-tail and display π-π inter-actions with a centroid-to-centroid distance of 3.6664 (8) Å. N-H⋯O hydrogen bonds between mol-ecules generate a 'step' structure through formation of an R 2 (2)(10) ring.
标题化合物C10H11N3O的分子是平面的，包括乙基，由N-C-C-C扭转角1.5 (2)°表明。在晶体中，与反演相关的分子沿a轴堆积。分子头对头排列，并显示质心到质心距离为3.6664 (8) Å的π-π相互作用。分子间的N-H⋯O氢键通过形成R 2 (2)(10)环产生一种“阶梯”结构。
