The material described by UThC2 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 Th(1)C6 octahedra, edges with six equivalent U(1)C6 octahedra, and edges with six equivalent Th(1)C6 octahedra. The corner-sharing octahedral tilt angles are 11°. Th(1) is bonded to six equivalent C(1) atoms to form ThC6 octahedra that share corners with six equivalent U(1)C6 octahedra, edges with six equivalent U(1)C6 octahedra, and edges with six equivalent Th(1)C6 octahedra. The corner-sharing octahedral tilt angles are 11°. C(1) is bonded to three equivalent U(1) and three equivalent Th(1) atoms to form a mixture of corner and edge-sharing CTh3U3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
