The structural characterisation of bis(8-sulfanylquinolinium) hexachloridostannate(iv) (2) is reported and the variable reaction behaviour of this compound in different solvents has been explored. In particular, attempted recrystallization of 2 from chloroform and dichloromethane affords two polymorphs of cis-dichloridobis(8-quinolinethiolato)tin(iv), 3m and 3t, respectively. Attempted recrystallization of 2 from methanol gives crystals of 8,8′-dithiodiquinolinium hexachloridostannate(iv) 4. When 2 is dissolved in dimethyl sulfoxide in the presence of air, it undergoes oxidation to afford diquinolinyl-8,8′-disulfide 5. The molecular structures of the isolated compounds 2–4 are unambiguously authenticated by single crystal X-ray diffraction studies. The electronic structure properties of all the isolated compounds 2–4 are thoroughly studied by DFT calculations.
