Abstract: 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-HO 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-HBr contacts.
