SnSb is Cyanogen Chloride-derived structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two SnSb clusters. Sn(1) is bonded in a linear geometry to one Sn(1) and one Sb(1) atom. The Sn(1)-Sn(1) bond length is 1.10 Å. The Sn(1)-Sb(1) bond length is 0.61 Å. Sb(1) is bonded in a single-bond geometry to one Sn(1) atom.
