Dichloridobis(pyridine-2-seleno-lato-?(2) N,Se)tin(IV).

ABSTRACT: The title compound, [SnCl2(C5H4NSe)2], is the product of a reaction of 2,2'-dipyridyl diselenide with tin tetra-chloride. The mol-ecule is located about a twofold rotation axis. The coordination environment of the Sn(IV) atom is a distorted octa-hedron, with two bidentate 2-pyridine-seleno-late 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, ?-? inter-actions between the pyridine rings [centroid-to-centroid distance of 3.758?(3)?Å] and weak inter-molecular C-H?Cl hydrogen bonds link the mol-ecules into chains along the c axis.
