Bis(2-carboxyquinolinium) hexachloridostannate(IV) dihydrate

Abstract

In the hydrated title salt, (C10H8NO2)2[SnCl6]·2H2O, the tin(IV) atom is located about a center of inversion. In the crystal structure, the organic cation, the octahedral inorganic anion and the water molecule of crystallization interact through O—H...O, N—H...O and O—H...Cl hydrogen bonds, supplemented by weak π–π stacking between neighboring cations, and C—Cl...π interactions.
