NpZn is Copper-derived structured and crystallizes in the hexagonal P-6m2 space group. Np(1) is bonded to six equivalent Np(1) and six equivalent Zn(1) atoms to form NpNp6Zn6 cuboctahedra that share corners with eighteen equivalent Np(1)Np6Zn6 cuboctahedra, edges with six equivalent Np(1)Np6Zn6 cuboctahedra, edges with twelve equivalent Zn(1)Np6Zn6 cuboctahedra, faces with eight equivalent Np(1)Np6Zn6 cuboctahedra, and faces with twelve equivalent Zn(1)Np6Zn6 cuboctahedra. Zn(1) is bonded to six equivalent Np(1) and six equivalent Zn(1) atoms to form ZnNp6Zn6 cuboctahedra that share corners with eighteen equivalent Zn(1)Np6Zn6 cuboctahedra, edges with six equivalent Zn(1)Np6Zn6 cuboctahedra, edges with twelve equivalent Np(1)Np6Zn6 cuboctahedra, faces with eight equivalent Zn(1)Np6Zn6 cuboctahedra, and faces with twelve equivalent Np(1)Np6Zn6 cuboctahedra.
