In Sn As As
InSnAs2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one InSnAs2 cluster. In(1) is bonded in a single-bond geometry to one Sn(1) atom. The In(1)-Sn(1) bond length is 2.15 Å. Sn(1) is bonded in a distorted bent 150 degrees geometry to one In(1) and one As(1) atom. The Sn(1)-As(1) bond length is 2.81 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a bent 150 degrees geometry to one Sn(1) and one As(2) atom. The As(1)-As(2) bond length is 1.76 Å. In the second As site, As(2) is bonded in a single-bond geometry to one As(1) atom.
