✦ Synopsis

The title compound, [Sn~4~(C~9~H~12~N)~4~S~6~]·CHCl~3~, consists of four [2-(Me~2~NCH~2~)C~6~H~4~]Sn units bridged by six S atoms along with a disordered solvent molecule. The cage-like structure has two four-membered Sn~2~S~2~ rings linked by two S atoms in an Sn~4~S~6~ skeleton. The asymmetry of the Sn—S bonds in the four-membered rings is the result of the combined effect of the trans influence of the strong N→ Sn intramolecular coordination as well as the Sn—S (axial and equatorial) bonds. The Sn atoms are pentacoordinated with a (C,N)SnS~3~ trigonal bipyramidal core. Owing to intermolecular H...Ph interactions, the molecules are arranged into a polymeric ribbon along the b axis of the monoclinic unit cell. The solvent Cl atoms are disordered over two positions; the site occupancies are 0.58 and 0.42.
