The material described by Pu3Zn is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Pu(1) is bonded to eight equivalent Pu(1) and four equivalent Zn(1) atoms to form distorted PuPu8Zn4 cuboctahedra that share corners with four equivalent Zn(1)Pu12 cuboctahedra, corners with fourteen equivalent Pu(1)Pu8Zn4 cuboctahedra, edges with six equivalent Zn(1)Pu12 cuboctahedra, edges with twelve equivalent Pu(1)Pu8Zn4 cuboctahedra, faces with four equivalent Zn(1)Pu12 cuboctahedra, and faces with sixteen equivalent Pu(1)Pu8Zn4 cuboctahedra. Zn(1) is bonded to twelve equivalent Pu(1) atoms to form ZnPu12 cuboctahedra that share corners with six equivalent Zn(1)Pu12 cuboctahedra, corners with twelve equivalent Pu(1)Pu8Zn4 cuboctahedra, edges with eighteen equivalent Pu(1)Pu8Zn4 cuboctahedra, faces with eight equivalent Zn(1)Pu12 cuboctahedra, and faces with twelve equivalent Pu(1)Pu8Zn4 cuboctahedra. is represented by the CIF file [CIF]
