ScZn2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Sc(1) is bonded in a 16-coordinate geometry to four equivalent Sc(1), three equivalent Zn(1), and nine equivalent Zn(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to six equivalent Sc(1) and six equivalent Zn(2) atoms to form a mixture of corner, face, and edge-sharing ZnSc6Zn6 cuboctahedra. In the second Zn site, Zn(2) is bonded to six equivalent Sc(1), two equivalent Zn(1), and four equivalent Zn(2) atoms to form a mixture of corner, face, and edge-sharing ZnSc6Zn6 cuboctahedra.
ScZn2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Sc(1) is bonded in a 16-coordinate geometry to four equivalent Sc(1), three equivalent Zn(1), and nine equivalent Zn(2) atoms. There is one shorter (3.18 Å) and three longer (3.19 Å) Sc(1)-Sc(1) bond lengths. All Sc(1)-Zn(1) bond lengths are 3.06 Å. There are three shorter (3.01 Å) and six longer (3.06 Å) Sc(1)-Zn(2) bond lengths. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to six equivalent Sc(1) and six equivalent Zn(2) atoms to form a mixture of corner, face, and edge-sharing ZnSc6Zn6 cuboctahedra. All Zn(1)-Zn(2) bond lengths are 2.61 Å. In the second Zn site, Zn(2) is bonded to six equivalent Sc(1), two equivalent Zn(1), and four equivalent Zn(2) atoms to form a mixture of corner, face, and edge-sharing ZnSc6Zn6 cuboctahedra. There are two shorter (2.55 Å) and two longer (2.68 Å) Zn(2)-Zn(2) bond lengths.
