The structure described by AgZn2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Ag(1) is bonded in a 16-coordinate geometry to four equivalent Ag(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 Ag(1) and six equivalent Zn(2) atoms to form a mixture of corner, edge, and face-sharing ZnZn6Ag6 cuboctahedra. In the second Zn site, Zn(2) is bonded to six equivalent Ag(1), two equivalent Zn(1), and four equivalent Zn(2) atoms to form a mixture of corner, edge, and face-sharing ZnZn6Ag6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
