Li In In Ge
LiIn2Ge is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LiIn2Ge clusters. Li(1) is bonded in a 3-coordinate geometry to two equivalent In(1) and one Ge(1) atom. Both Li(1)-In(1) bond lengths are 1.33 Å. The Li(1)-Ge(1) bond length is 1.41 Å. In(1) is bonded in a 2-coordinate geometry to one Li(1) and one Ge(1) atom. The In(1)-Ge(1) bond length is 1.33 Å. Ge(1) is bonded in a 3-coordinate geometry to one Li(1) and two equivalent In(1) atoms.
