InAl2Sn is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two InAl2Sn clusters. In(1) is bonded in an L-shaped geometry to two equivalent Al(1) atoms. Both In(1)-Al(1) bond lengths are 1.52 Å. Al(1) is bonded in a distorted L-shaped geometry to one In(1) and one Sn(1) atom. The Al(1)-Sn(1) bond length is 1.52 Å. Sn(1) is bonded in an L-shaped geometry to two equivalent Al(1) atoms.
