Materials Data on HoNp3 by Materials Project
Np3Ho is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Np is bonded to eight equivalent Np and four equivalent Ho atoms to form NpHo4Np8 cuboctahedra that share corners with twelve equivalent NpHo4Np8 cuboctahedra, edges with eight equivalent HoNp12 cuboctahedra, edges with sixteen equivalent NpHo4Np8 cuboctahedra, faces with four equivalent HoNp12 cuboctahedra, and faces with fourteen equivalent NpHo4Np8 cuboctahedra. All Np–Np bond lengths are 3.28 Å. All Np–Ho bond lengths are 3.28 Å. Ho is bonded to twelve equivalent Np atoms to form HoNp12 cuboctahedra that share corners with twelve equivalent HoNp12 cuboctahedra, edges with twenty-four equivalent NpHo4Np8 cuboctahedra, faces with six equivalent HoNp12 cuboctahedra, and faces with twelve equivalent NpHo4Np8 cuboctahedra.
