Materials Data on LaUN2 by Materials Project
ULaN2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. U3+ is bonded to six equivalent N3- atoms to form UN6 octahedra that share corners with six equivalent LaN6 octahedra, edges with six equivalent UN6 octahedra, and edges with six equivalent LaN6 octahedra. The corner-sharing octahedral tilt angles are 12°. All U–N bond lengths are 2.35 Å. La3+ is bonded to six equivalent N3- atoms to form LaN6 octahedra that share corners with six equivalent UN6 octahedra, edges with six equivalent UN6 octahedra, and edges with six equivalent LaN6 octahedra. The corner-sharing octahedral tilt angles are 12°. All La–N bond lengths are 2.72 Å. N3- is bonded to three equivalent U3+ and three equivalent La3+ atoms to form a mixture of edge and corner-sharing NLa3U3 octahedra. The corner-sharing octahedral tilt angles are 0°.
