Sn Sb As As
SnSbAs2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SnSbAs2 cluster. Sn(1) is bonded in a single-bond geometry to one Sb(1) atom. The Sn(1)-Sb(1) bond length is 1.41 Å. Sb(1) is bonded in a 3-coordinate geometry to one Sn(1), one As(1), and one As(2) atom. The Sb(1)-As(1) bond length is 0.92 Å. The Sb(1)-As(2) bond length is 1.67 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 single-bond geometry to one Sb(1) atom.
