The material described by LiTbGe crystallizes in the hexagonal P-62m space group. Li(1) is bonded to two equivalent Ge(1) and two equivalent Ge(2) atoms to form a mixture of distorted corner and edge-sharing LiGe4 tetrahedra. Tb(1) is bonded in a 5-coordinate geometry to one Ge(1) and four equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Li(1) and three equivalent Tb(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Li(1) and six equivalent Tb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
