SmZnGe crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded to six equivalent Zn(1) and six equivalent Ge(1) atoms to form a mixture of distorted face and edge-sharing SmZn6Ge6 cuboctahedra. In the second Sm site, Sm(2) is bonded to six equivalent Zn(1) and six equivalent Ge(1) atoms to form a mixture of distorted face and edge-sharing SmZn6Ge6 cuboctahedra. Zn(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1), three equivalent Sm(2), and three equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1), three equivalent Sm(2), and three equivalent Zn(1) atoms.
