UCeN2 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 CeN6 octahedra, edges with six equivalent UN6 octahedra, and edges with six equivalent CeN6 octahedra. The corner-sharing octahedral tilt angles are 7°. All U–N bond lengths are 2.38 Å. Ce3+ is bonded to six equivalent N3- atoms to form CeN6 octahedra that share corners with six equivalent UN6 octahedra, edges with six equivalent UN6 octahedra, and edges with six equivalent CeN6 octahedra. The corner-sharing octahedral tilt angles are 7°. All Ce–N bond lengths are 2.58 Å. N3- is bonded to three equivalent U3+ and three equivalent Ce3+ atoms to form a mixture of corner and edge-sharing NCe3U3 octahedra. The corner-sharing octahedral tilt angles are 0°.
