Three supramolecular bromostannates(IV) with "trapped" diiodine molecules, Cat 2 {[SnBr 6 ](I 2 )} (Cat = Me 4 N + ( 1 ), 1-MePy + ( 2 ) and 4-MePyH ( 3 )), were synthesized. In all cases, I 2 linkers are connected with bromide ligands via halogen···halogen non-covalent interactions. Articles 1-3 were studied using Raman spectroscopy, thermogravimetric analysis, and diffuse reflectance spectroscopy. The latter indicates that 1-3 are narrow band gap semiconductors.
