Ag2SbBr is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ag2SbBr clusters. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Br(1) atom. The Ag(1)-Br(1) bond length is 0.23 Å. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one Sb(1) atom. The Ag(2)-Sb(1) bond length is 3.39 Å. Sb(1) is bonded in a single-bond geometry to one Ag(2) and one Br(1) atom. The Sb(1)-Br(1) bond length is 1.03 Å. Br(1) is bonded in a single-bond geometry to one Ag(1) and one Sb(1) atom.
