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

摘要

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.
