The material structure described by SrZn5 crystallizes in the hexagonal P6/mmm space group. Sr(1) is bonded in a 18-coordinate geometry to six equivalent Zn(1) and twelve equivalent Zn(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 9-coordinate geometry to three equivalent Sr(1) and six equivalent Zn(2) atoms. In the second Zn site, Zn(2) is bonded to four equivalent Sr(1), four equivalent Zn(1), and four equivalent Zn(2) atoms to form a mixture of face, corner, and edge-sharing ZnSr4Zn8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
