LaCr2Sn is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaCr2Sn clusters. La(1) is bonded in an L-shaped geometry to two equivalent Cr(1) atoms. Both La(1)-Cr(1) bond lengths are 1.53 Å. Cr(1) is bonded in a distorted L-shaped geometry to one La(1) and one Sn(1) atom. The Cr(1)-Sn(1) bond length is 1.53 Å. Sn(1) is bonded in an L-shaped geometry to two equivalent Cr(1) atoms.
