Abstract: The title compound, [SnCl2(C5H4NSe)2], is the product of a reaction of 2,2'-dipyridyl diselenide with tin tetrachloride. The molecule is located about a twofold rotation axis. The coordination environment of the SnIV atom is a distorted octahedron, with two bidentate 2-pyridineselenolate ligands inclined to each other at an angle of 83.96 (7)°. The two Sn-Cl and two Sn-N bonds are in cis configurations, while the two Sn-Se bonds of 2.5917 (3) Å are in a trans configuration, with an Se-Sn-Se angle of 157.988 (15)°. In the crystal, [pi]-[pi] interactions between the pyridine rings [centroid-to-centroid distance of 3.758 (3) Å] and weak intermolecular C-H...Cl hydrogen bonds link the molecules into chains along the c axis.
