The title compound, [SnCl4(C10H8N2Se)], was obtained by the reaction of 2,2′-dipyridyl diselenide with tin tetrachloride. The SnIV 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.
