The material described by AgZn3 is beta-derived structured and crystallizes in the hexagonal P-6m2 space group. Ag(1) is bonded to six equivalent Ag(1) and six equivalent Zn(2) atoms to form distorted AgZn6Ag6 cuboctahedra that share corners with six equivalent Ag(1)Zn6Ag6 cuboctahedra, corners with twelve equivalent Zn(1)Zn12 cuboctahedra, edges with six equivalent Ag(1)Zn6Ag6 cuboctahedra, edges with twelve equivalent Zn(2)Zn9Ag3 cuboctahedra, faces with two equivalent Zn(1)Zn12 cuboctahedra, faces with six equivalent Ag(1)Zn6Ag6 cuboctahedra, and faces with twelve equivalent Zn(2)Zn9Ag3 cuboctahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to six equivalent Zn(1) and six equivalent Zn(2) atoms to form ZnZn12 cuboctahedra that share corners with six equivalent Zn(1)Zn12 cuboctahedra, corners with twelve equivalent Ag(1)Zn6Ag6 cuboctahedra, edges with six equivalent Zn(1)Zn12 cuboctahedra, edges with twelve equivalent Zn(2)Zn9Ag3 cuboctahedra, faces with two equivalent Ag(1)Zn6Ag6 cuboctahedra, faces with six equivalent Zn(1)Zn12 cuboctahedra, and faces with twelve equivalent Zn(2)Zn9Ag3 cuboctahedra. In the second Zn site, Zn(2) is bonded to three equivalent Ag(1), three equivalent Zn(1), and six equivalent Zn(2) atoms to form distorted ZnZn9Ag3 cuboctahedra that share corners with eighteen equivalent Zn(2)Zn9Ag3 cuboctahedra, edges with six equivalent Ag(1)Zn6Ag6 cuboctahedra, edges with six equivalent Zn(1)Zn12 cuboctahedra, edges with six equivalent Zn(2)Zn9Ag3 cuboctahedra, faces with six equivalent Ag(1)Zn6Ag6 cuboctahedra, faces with six equivalent Zn(1)Zn12 cuboctahedra, and faces with eight equivalent Zn(2)Zn9Ag3 cuboctahedra. is represented by the CIF file [CIF]
