NpCd is Copper-derived structured and crystallizes in the orthorhombic Amm2 space group. Np(1) is bonded to six equivalent Np(1) and six equivalent Cd(1) atoms to form NpNp6Cd6 cuboctahedra that share corners with eighteen equivalent Np(1)Np6Cd6 cuboctahedra, edges with six equivalent Np(1)Np6Cd6 cuboctahedra, edges with twelve equivalent Cd(1)Np6Cd6 cuboctahedra, faces with eight equivalent Np(1)Np6Cd6 cuboctahedra, and faces with twelve equivalent Cd(1)Np6Cd6 cuboctahedra. Cd(1) is bonded to six equivalent Np(1) and six equivalent Cd(1) atoms to form CdNp6Cd6 cuboctahedra that share corners with eighteen equivalent Cd(1)Np6Cd6 cuboctahedra, edges with six equivalent Cd(1)Np6Cd6 cuboctahedra, edges with twelve equivalent Np(1)Np6Cd6 cuboctahedra, faces with eight equivalent Cd(1)Np6Cd6 cuboctahedra, and faces with twelve equivalent Np(1)Np6Cd6 cuboctahedra.
