LiYGe 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 edge and corner-sharing LiGe4 tetrahedra. Y(1) is bonded in a 5-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to six equivalent Li(1) and three equivalent Y(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Li(1) and six equivalent Y(1) atoms.
LiYGe 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 edge and corner-sharing LiGe4 tetrahedra. Both Li(1)-Ge(1) bond lengths are 2.79 Å. Both Li(1)-Ge(2) bond lengths are 2.68 Å. Y(1) is bonded in a 5-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. The Y(1)-Ge(2) bond length is 2.99 Å. All Y(1)-Ge(1) bond lengths are 2.99 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to six equivalent Li(1) and three equivalent Y(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Li(1) and six equivalent Y(1) atoms.
