Bis[2,2′-(2-aminoethylimino)di(ethylammonium)] di-μ-sulfido-bis[disulfidostannate(IV)]

Abstract

The asymmetric unit of the title compound, (C6H20N4)2[Sn2S6], comprises half of a [Sn2S6]4− anion and a diprotonated tris(2-aminoethyl)amine cation. The anion lies on an inversion center, while the atoms of the cation occupy general positions. An intramolecular N—H...N hydrogen bond is observed in the cation. In the crystal, strong N—H...S hydrogen bonding between the terminal sulfur atoms of the anion and the protonated amine N atoms of the cations result in a three-dimensional network.
