Li Cu Sn Sn
LiCuSn2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one LiCuSn2 cluster. Li(1) is bonded in a linear geometry to one Cu(1) and one Sn(1) atom. The Li(1)-Cu(1) bond length is 1.67 Å. The Li(1)-Sn(1) bond length is 0.81 Å. Cu(1) is bonded in a linear geometry to one Li(1) and one Sn(2) atom. The Cu(1)-Sn(2) bond length is 0.76 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a single-bond geometry to one Li(1) atom. In the second Sn site, Sn(2) is bonded in a single-bond geometry to one Cu(1) atom.
