LiSmGe 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. Sm(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 Sm(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Li(1) and six equivalent Sm(1) atoms.
LiSmGe 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. Both Li(1)-Ge(1) bond lengths are 2.84 Å. Both Li(1)-Ge(2) bond lengths are 2.73 Å. Sm(1) is bonded in a 5-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. The Sm(1)-Ge(2) bond length is 3.03 Å. All Sm(1)-Ge(1) bond lengths are 3.05 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 Sm(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Li(1) and six equivalent Sm(1) atoms.
