The Ni(II) atom in the title complex, [Ni(C₁₁H₁₃N₃OS)(C₅H₅N)], exists within a square-planar N₃O donor set provided by N,N',O atoms of the dianionic tridentate ligand and a pyridine N atom. The maximum deviation from the ideal geometry is seen in the N-Ni-N five-membered chelate bite angle of 83.28 (12)°. The pyridine mol-ecule forms a dihedral angle of 44.43 (6)° with the N₃O donor set. Supra-molecular stacks along the a axis mediated by alternating π-π inter-actions between the pyridine and five- [centroid-centroid distance = 3.4784 (16) Å] and six-membered [3.4633 (17) Å] chelate rings, feature in the crystal packing.
在标题配合物[Ni(C₁₁H₁₃N₃OS)(C₅H₅N)]中，Ni(II)原子存在于由双齿三齿配体的N、N'、O原子和吡啶N原子提供的平面四边形N₃O供体集合内。与理想几何形状的最大偏差出现在N-Ni-N五元螯合咬角为83.28 (12)°时。吡啶分子与N₃O供体集合形成44.43 (6)°的二面角。晶体堆积的特征是沿着a轴通过吡啶与五元[质心-质心距离 = 3.4784 (16) Å]和六元[3.4633 (17) Å]螯合环之间交替的π-π相互作用介导的超分子堆积。
