UZrN2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. U(1) is bonded to six N(1,1) atoms to form UN6 octahedra that share corners with two equivalent Zr(1)N6 octahedra, corners with four equivalent U(1)N6 octahedra, edges with four equivalent U(1)N6 octahedra, and edges with eight equivalent Zr(1)N6 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. Zr(1) is bonded to six N(1,1) atoms to form ZrN6 octahedra that share corners with two equivalent U(1)N6 octahedra, corners with four equivalent Zr(1)N6 octahedra, edges with four equivalent Zr(1)N6 octahedra, and edges with eight equivalent U(1)N6 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent U(1) and three equivalent Zr(1) atoms to form a mixture of corner and edge-sharing NZr3U3 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. In the second N site, N(1) is bonded to three equivalent U(1) and three equivalent Zr(1) atoms to form a mixture of corner and edge-sharing NZr3U3 octahedra. The corner-sharing octahedral tilt angles range from 0-1°.
