Bis[2-(ethoxy-carbonyl-amino)ethan-aminium] hexa-bromidostannate.

In the title salt, (C5H13N2O2)2[SnBr6], the Sn atom (site symmetry \overline{1}) exists in a slightly distorted octa­hedral geometry. The cation is non-planar as the terminal CH2NH3+ residue lies below the plane defined by the remaining non-H atoms. In the crystal, cations associate via N—H⋯O hydrogen bonds involving the ammonium and carbonyl residues, forming a 14-membered {⋯HNC2NCO}2 synthon. The cations and anions are arranged in alternating layers arranged along the a-axis direction, the major association between them being N—H⋯Br contacts.
