UZrC2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. U(1) is bonded to six equivalent C(1) atoms to form UC6 octahedra that share corners with six equivalent Zr(1)C6 octahedra, edges with six equivalent U(1)C6 octahedra, and edges with six equivalent Zr(1)C6 octahedra. The corner-sharing octahedra are not tilted. Zr(1) is bonded to six equivalent C(1) atoms to form ZrC6 octahedra that share corners with six equivalent U(1)C6 octahedra, edges with six equivalent U(1)C6 octahedra, and edges with six equivalent Zr(1)C6 octahedra. The corner-sharing octahedra are not tilted. C(1) is bonded to three equivalent U(1) and three equivalent Zr(1) atoms to form a mixture of corner and edge-sharing CZr3U3 octahedra. The corner-sharing octahedra are not tilted.
