In the title compound, C(6)H(7)N(3)O(2), the dihedral angle between the nitro group and the pyridine ring is 15.5 (3)° and an intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, inversion dimers linked by two N-H⋯N hydrogen bonds occur, resulting in R(2) (2)(8) rings. The packing is stabilized by aromatic π-π stacking [centroid-centroid distance = 3.5666 (15) Å] and a short N-O⋯π contact is seen.
在标题化合物C(6)H(7)N(3)O(2)中,硝基与吡啶环之间的二面角为15.5 (3)°,并且存在分子内N-H⋯O氢键。在晶体中,通过两个N-H⋯N氢键连接形成反演二聚体,产生R(2) (2)(8)环。堆积通过芳香π-π堆积[质心-质心距离 = 3.5666 (15) Å]得以稳定,并且观察到一个短的N-O⋯π接触。
