Tb3Zn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Tb(1) is bonded to eight equivalent Tb(1) and four equivalent Zn(1) atoms to form distorted TbTb8Zn4 cuboctahedra that share corners with twelve equivalent Tb(1)Tb8Zn4 cuboctahedra, edges with eight equivalent Zn(1)Tb12 cuboctahedra, edges with sixteen equivalent Tb(1)Tb8Zn4 cuboctahedra, faces with four equivalent Zn(1)Tb12 cuboctahedra, and faces with fourteen equivalent Tb(1)Tb8Zn4 cuboctahedra. Zn(1) is bonded to twelve equivalent Tb(1) atoms to form ZnTb12 cuboctahedra that share corners with twelve equivalent Zn(1)Tb12 cuboctahedra, edges with twenty-four equivalent Tb(1)Tb8Zn4 cuboctahedra, faces with six equivalent Zn(1)Tb12 cuboctahedra, and faces with twelve equivalent Tb(1)Tb8Zn4 cuboctahedra.
