The distorted octa-hedral geometry about the Sn(IV) atom in the title compound, [Sn(C(6)H(5))(2)(C(14)H(19)N(4)S)Cl], is defined by the N,N,S-tridentate Schiff base ligand, two mutually trans ipso-C atoms of the Sn-bound phenyl groups, and the Cl atom which is trans to the azo N atom. The two five-membered chelate rings and pyridyl ring are almost coplanar with the dihedral angle between the outer five-membered chelate and pyridine rings being 5.39 (8)°. Centrosymmetric dimers feature in the crystal packing mediated by N-H⋯S hydrogen bonds, leading to eight-membered {⋯HNCS}(2) synthons. The dimeric aggregates are connected into a three-dimensional architecture by C-H⋯Cl and C-H⋯π inter-actions, as well as π-π inter-actions occurring between centrosymmetrically related pyridine rings [centroid-centroid distance = 3.6322 (13) Å].
在标题化合物[Sn(C₆H₅)₂(C₁₄H₁₉N₄S)Cl]中,围绕Sn(IV)原子的扭曲八面体几何构型由N,N,S-三齿席夫碱配体、与Sn相连的苯基的两个相互反位的本位C原子以及与偶氮N原子反位的Cl原子所确定。两个五元螯合环和吡啶环几乎共面,外部五元螯合环与吡啶环之间的二面角为5.39 (8)°。晶体堆积中存在由N-H⋯S氢键介导的中心对称二聚体,形成八元{⋯HNCS}₂合成子。二聚聚集体通过C-H⋯Cl和C-H⋯π相互作用以及中心对称相关吡啶环之间的π-π相互作用[质心-质心距离 = 3.6322 (13) Å]连接成三维结构。
