[Bis(pyridin-2-yl) selenide-κ(2) N,N′]tetra­chloridotin(IV)

The title compound, [SnCl(4)(C(10)H(8)N(2)Se)], was obtained by the reaction of 2,2′-dipyridyl diselenide with tin tetra­chloride. The Sn(IV) ion is coordinated by two N atoms [Sn—N = 2.266 (2) and 2.274 (2) Å] from the bis­(2-pyrid­yl)selenide ligand and four chloride anions [Sn—Cl = 2.3717 (6)–2.3939 (6) Å] in a distorted octa­hedral geometry. The central six-membered chelate ring has a boat conformation with the Se and Sn atoms deviating by 0.692 (3) and 0.855 (3) Å, respectively, from the mean plane through the remaining four ring atoms. The pyridine rings are inclined to each other by a dihedral angle of 49.62 (8)°. The crystal packing exhibits short inter­molecular Se⋯Cl contacts [3.5417 (7) and 3.5648 (7) Å], weak C—H⋯Cl hydrogen bonds and π–π stacking inter­actions between the pyridine rings with a centroid–centroid distance of 3.683 (3) Å.
