Chlorido{4-cyclo­hexyl-1-[1-(pyridin-2-yl-κN)ethyl­idene]thio­semicarbazidato-κ²N¹,S}diphenyl­tin(IV)

The distorted octa­hedral geometry about the Sn^IV atom in the title compound, [Sn(C₆H₅)₂(C₁₄H₁₉N₄S)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 inter­actions, as well as π–π inter­actions occurring between centrosymmetrically related pyridine rings [centroid–centroid distance = 3.6322 (13) Å].
