Li Sn Sb Sb
LiSnSb2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LiSnSb2 clusters. Li(1) is bonded in a distorted water-like geometry to one Sn(1) and two equivalent Sb(1) atoms. The Li(1)-Sn(1) bond length is 2.51 Å. Both Li(1)-Sb(1) bond lengths are 1.64 Å. Sn(1) is bonded in a distorted single-bond geometry to one Li(1) atom. Sb(1) is bonded in a single-bond geometry to one Li(1) atom.
