SrZn2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded in a 12-coordinate geometry to three equivalent Zn(2) and nine equivalent Zn(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(2) is bonded to six equivalent Sr(1) and six equivalent Zn(1) atoms to form a mixture of face and edge-sharing ZnSr6Zn6 cuboctahedra. In the second Zn site, Zn(1) is bonded in a 10-coordinate geometry to six equivalent Sr(1), two equivalent Zn(1), and two equivalent Zn(2) atoms.
SrZn2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded in a 12-coordinate geometry to three equivalent Zn(2) and nine equivalent Zn(1) atoms. All Sr(1)-Zn(2) bond lengths are 3.43 Å. There are three shorter (3.25 Å) and six longer (3.44 Å) Sr(1)-Zn(1) bond lengths. There are two inequivalent Zn sites. In the first Zn site, Zn(2) is bonded to six equivalent Sr(1) and six equivalent Zn(1) atoms to form a mixture of face and edge-sharing ZnSr6Zn6 cuboctahedra. All Zn(2)-Zn(1) bond lengths are 2.72 Å. In the second Zn site, Zn(1) is bonded in a 10-coordinate geometry to six equivalent Sr(1), two equivalent Zn(1), and two equivalent Zn(2) atoms. Both Zn(1)-Zn(1) bond lengths are 2.70 Å.
