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

Abstract

The distorted octahedral geometry about the SnIVatom in the title compound, [Sn(C6H5)2(C14H19N4S)Cl], is defined by theN,N,S-tridentate Schiff base ligand, two mutuallytrans ipso-C atoms of the Sn-bound phenyl groups, and the Cl atom which istransto 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}2synthons. 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].
