Al Al Sn Bi
Al2SnBi is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Al2SnBi clusters. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a single-bond geometry to one Sn(1) atom. The Al(1)-Sn(1) bond length is 1.64 Å. In the second Al site, Al(2) is bonded in a single-bond geometry to one Bi(1) atom. The Al(2)-Bi(1) bond length is 1.72 Å. Sn(1) is bonded in a distorted single-bond geometry to one Al(1) and one Bi(1) atom. The Sn(1)-Bi(1) bond length is 0.12 Å. Bi(1) is bonded in a distorted single-bond geometry to one Al(2) and one Sn(1) atom.
