The crystal structure described by Np3Gd 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 Gd(1) atoms to form NpGd4Np8 cuboctahedra that share corners with twelve equivalent Np(1)Gd4Np8 cuboctahedra, edges with eight equivalent Gd(1)Np12 cuboctahedra, edges with sixteen equivalent Np(1)Gd4Np8 cuboctahedra, faces with four equivalent Gd(1)Np12 cuboctahedra, and faces with fourteen equivalent Np(1)Gd4Np8 cuboctahedra. Gd(1) is bonded to twelve equivalent Np(1) atoms to form GdNp12 cuboctahedra that share corners with twelve equivalent Gd(1)Np12 cuboctahedra, edges with twenty-four equivalent Np(1)Gd4Np8 cuboctahedra, faces with six equivalent Gd(1)Np12 cuboctahedra, and faces with twelve equivalent Np(1)Gd4Np8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
