SmGe3 crystallizes in the hexagonal P6_3/mmc space group. Sm(1) is bonded to twelve equivalent Ge(1) atoms to form a mixture of face and corner-sharing SmGe12 cuboctahedra. Ge(1) is bonded in a 10-coordinate geometry to four equivalent Sm(1) and six equivalent Ge(1) atoms.
SmGe3 crystallizes in the hexagonal P6_3/mmc space group. Sm(1) is bonded to twelve equivalent Ge(1) atoms to form a mixture of face and corner-sharing SmGe12 cuboctahedra. There are six shorter (3.07 Å) and six longer (3.26 Å) Sm(1)-Ge(1) bond lengths. Ge(1) is bonded in a 10-coordinate geometry to four equivalent Sm(1) and six equivalent Ge(1) atoms. There are two shorter (2.72 Å) and four longer (3.05 Å) Ge(1)-Ge(1) bond lengths.
