Materials Data on GdNp3 by Materials Project
Np3Gd 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 Gd atoms to form NpGd4Np8 cuboctahedra that share corners with twelve equivalent NpGd4Np8 cuboctahedra, edges with eight equivalent GdNp12 cuboctahedra, edges with sixteen equivalent NpGd4Np8 cuboctahedra, faces with four equivalent GdNp12 cuboctahedra, and faces with fourteen equivalent NpGd4Np8 cuboctahedra. All Np–Np bond lengths are 3.26 Å. All Np–Gd bond lengths are 3.26 Å. Gd is bonded to twelve equivalent Np atoms to form GdNp12 cuboctahedra that share corners with twelve equivalent GdNp12 cuboctahedra, edges with twenty-four equivalent NpGd4Np8 cuboctahedra, faces with six equivalent GdNp12 cuboctahedra, and faces with twelve equivalent NpGd4Np8 cuboctahedra.
