UZrN2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. U(1) is bonded to six equivalent N(1) atoms to form UN6 octahedra that share corners with six equivalent Zr(1)N6 octahedra, edges with six equivalent U(1)N6 octahedra, and edges with six equivalent Zr(1)N6 octahedra. The corner-sharing octahedral tilt angles are 5°. Zr(1) is bonded to six equivalent N(1) atoms to form ZrN6 octahedra that share corners with six equivalent U(1)N6 octahedra, edges with six equivalent U(1)N6 octahedra, and edges with six equivalent Zr(1)N6 octahedra. The corner-sharing octahedral tilt angles are 5°. N(1) is bonded to three equivalent U(1) and three equivalent Zr(1) atoms to form a mixture of edge and corner-sharing NZr3U3 octahedra. The corner-sharing octahedra are not tilted.
