SnSbAs2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SnSbAs2 clusters. Sn(1) is bonded in a single-bond geometry to one As(2) atom. The Sn(1)-As(2) bond length is 0.41 Å. Sb(1) is bonded in a linear geometry to one As(1) and one As(2) atom. The Sb(1)-As(1) bond length is 0.40 Å. The Sb(1)-As(2) bond length is 0.40 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a single-bond geometry to one Sb(1) atom. In the second As site, As(2) is bonded in a linear geometry to one Sn(1) and one Sb(1) atom.
