Materials Data on HoNp by Materials Project
NpHo is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Np is bonded to six equivalent Np and six equivalent Ho atoms to form NpHo6Np6 cuboctahedra that share corners with eighteen equivalent NpHo6Np6 cuboctahedra, edges with six equivalent NpHo6Np6 cuboctahedra, edges with twelve equivalent HoHo6Np6 cuboctahedra, faces with eight equivalent NpHo6Np6 cuboctahedra, and faces with twelve equivalent HoHo6Np6 cuboctahedra. All Np–Np bond lengths are 3.29 Å. All Np–Ho bond lengths are 3.47 Å. Ho is bonded to six equivalent Np and six equivalent Ho atoms to form HoHo6Np6 cuboctahedra that share corners with eighteen equivalent HoHo6Np6 cuboctahedra, edges with six equivalent HoHo6Np6 cuboctahedra, edges with twelve equivalent NpHo6Np6 cuboctahedra, faces with eight equivalent HoHo6Np6 cuboctahedra, and faces with twelve equivalent NpHo6Np6 cuboctahedra. All Ho–Ho bond lengths are 3.29 Å.
