Sc Si Sn Sn
ScSn2Si crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ScSn2Si cluster. Sc(1) is bonded in a bent 150 degrees geometry to one Sn(1) and one Sn(2) atom. The Sc(1)-Sn(1) bond length is 1.72 Å. The Sc(1)-Sn(2) bond length is 1.72 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a bent 150 degrees geometry to one Sc(1) and one Si(1) atom. The Sn(1)-Si(1) bond length is 0.87 Å. In the second Sn site, Sn(2) is bonded in a single-bond geometry to one Sc(1) atom. Si(1) is bonded in a single-bond geometry to one Sn(1) atom.
