The material structure described by Np3Sn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Np(1) is bonded to eight equivalent Np(1) and four equivalent Sn(1) atoms to form distorted NpNp8Sn4 cuboctahedra that share corners with twelve equivalent Np(1)Np8Sn4 cuboctahedra, edges with eight equivalent Sn(1)Np12 cuboctahedra, edges with sixteen equivalent Np(1)Np8Sn4 cuboctahedra, faces with four equivalent Sn(1)Np12 cuboctahedra, and faces with fourteen equivalent Np(1)Np8Sn4 cuboctahedra. Sn(1) is bonded to twelve equivalent Np(1) atoms to form SnNp12 cuboctahedra that share corners with twelve equivalent Sn(1)Np12 cuboctahedra, edges with twenty-four equivalent Np(1)Np8Sn4 cuboctahedra, faces with six equivalent Sn(1)Np12 cuboctahedra, and faces with twelve equivalent Np(1)Np8Sn4 cuboctahedra. is represented by the CIF file [CIF]
