LiLuGe 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. Lu(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 Lu(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Li(1) and six equivalent Lu(1) atoms.
LiLuGe 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 2.71 Å. Both Li(1)-Ge(2) bond lengths are 2.62 Å. Lu(1) is bonded in a 5-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. The Lu(1)-Ge(2) bond length is 2.94 Å. All Lu(1)-Ge(1) bond lengths are 2.92 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 Lu(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Li(1) and six equivalent Lu(1) atoms.
