Ag2SnBr is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ag2SnBr clusters. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted linear geometry to one Sn(1) and one Br(1) atom. The Ag(1)-Sn(1) bond length is 0.08 Å. The Ag(1)-Br(1) bond length is 0.06 Å. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Sn(1) atom. The Ag(2)-Sn(1) bond length is 0.08 Å. Sn(1) is bonded in a linear geometry to one Ag(1) and one Ag(2) atom. Br(1) is bonded in a single-bond geometry to one Ag(1) atom.
