The title compound, C(15)H(16)N(4)S, exists in the Z conformation with the thionyl S atom lying cis to the azomethine N atom. The shortening of the N-N distance [1.3697 (17) Å] is due to extensive delocalization with the pyridine ring. The hydrazine-carbothio-amide unit is almost planar, with a maximum deviation of 0.013 (2) Å for the amide N atom. The stability of this conformation is favoured by the formation of an intra-molecular N-H⋯N hydrogen bond. The packing of the mol-ecules involves no classical inter-molecular hydrogen-bonding inter-actions; however, a C-H⋯π inter-action occurs.
标题化合物C(15)H(16)N(4)S以Z构象存在，亚硫酰基S原子与偶氮甲碱N原子呈顺式排列。N-N键长缩短[1.3697 (17) Å]是由于与吡啶环的广泛离域作用。肼基碳硫酰胺单元几乎呈平面状，酰胺N原子的最大偏差为0.013 (2) Å。这种构象的稳定性得益于分子内N-H⋯N氢键的形成。分子堆积不涉及经典的分子间氢键相互作用；然而，存在C-H⋯π相互作用。
