Materials Data on CsNp3 by Materials Project
CsNp3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Cs is bonded to twelve equivalent Np atoms to form CsNp12 cuboctahedra that share corners with twelve equivalent CsNp12 cuboctahedra, edges with twenty-four equivalent NpCs4Np8 cuboctahedra, faces with six equivalent CsNp12 cuboctahedra, and faces with twelve equivalent NpCs4Np8 cuboctahedra. All Cs–Np bond lengths are 3.30 Å. Np is bonded to four equivalent Cs and eight equivalent Np atoms to form distorted NpCs4Np8 cuboctahedra that share corners with twelve equivalent NpCs4Np8 cuboctahedra, edges with eight equivalent CsNp12 cuboctahedra, edges with sixteen equivalent NpCs4Np8 cuboctahedra, faces with four equivalent CsNp12 cuboctahedra, and faces with fourteen equivalent NpCs4Np8 cuboctahedra. All Np–Np bond lengths are 3.30 Å.
