The structure described by ThCeC2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Th(1) is bonded to six equivalent C(1) atoms to form ThC6 octahedra that share corners with six equivalent Ce(1)C6 octahedra, edges with six equivalent Th(1)C6 octahedra, and edges with six equivalent Ce(1)C6 octahedra. The corner-sharing octahedral tilt angles are 1°. Ce(1) is bonded to six equivalent C(1) atoms to form CeC6 octahedra that share corners with six equivalent Th(1)C6 octahedra, edges with six equivalent Th(1)C6 octahedra, and edges with six equivalent Ce(1)C6 octahedra. The corner-sharing octahedral tilt angles are 1°. C(1) is bonded to three equivalent Th(1) and three equivalent Ce(1) atoms to form a mixture of corner and edge-sharing CCe3Th3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
