CsNp3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Cs(1) is bonded to twelve equivalent Np(1) atoms to form CsNp12 cuboctahedra that share corners with twelve equivalent Cs(1)Np12 cuboctahedra, edges with twenty-four equivalent Np(1)Cs4Np8 cuboctahedra, faces with six equivalent Cs(1)Np12 cuboctahedra, and faces with twelve equivalent Np(1)Cs4Np8 cuboctahedra. Np(1) is bonded to four equivalent Cs(1) and eight equivalent Np(1) atoms to form distorted NpCs4Np8 cuboctahedra that share corners with twelve equivalent Np(1)Cs4Np8 cuboctahedra, edges with eight equivalent Cs(1)Np12 cuboctahedra, edges with sixteen equivalent Np(1)Cs4Np8 cuboctahedra, faces with four equivalent Cs(1)Np12 cuboctahedra, and faces with fourteen equivalent Np(1)Cs4Np8 cuboctahedra.
