Two independent mol-ecules comprise the asymmetric unit in the title compound, [Sn(C₄H₉)(C₁₄H₁₉N₄S)Cl₂]. In each mol-ecule, the Sn(IV) atom exists within a distorted octa-hedral geometry defined by the N,N',S-tridentate mono-deprotonated Schiff base ligand, two mutually trans Cl atoms, and the α-C atom of the n-butyl group; the latter is trans to the azo-N atom. The greatest distortion from the ideal geometry is found in the nominally trans angle formed by the S and pyridyl-N atoms at Sn [151.72 (7) and 152.04 (7)°, respectively]. In the crystal, mol-ecules are consolidated into a three-dimensional architecture by a combination of N-H⋯Cl, C-H⋯π and π-π inter-actions [inter-centroid distances = 3.6718 (19) and 3.675 (2) Å].
在标题化合物[Sn(C₄H₉)(C₁₄H₁₉N₄S)Cl₂]中，不对称单元由两个独立的分子组成。在每个分子中，Sn(IV)原子存在于由N,N',S-三齿单去质子化席夫碱配体、两个相互反位的Cl原子以及正丁基的α-C原子所定义的扭曲八面体几何构型中；后者与偶氮-N原子反位。从理想几何构型的最大扭曲出现在Sn处由S和吡啶基-N原子形成的名义上的反位角[分别为151.72 (7)°和152.04 (7)°]。在晶体中，分子通过N-H⋯Cl、C-H⋯π和π-π相互作用[质心间距 = 3.6718 (19)和3.675 (2) Å]结合成三维结构。
