UThS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. U(1) is bonded to six equivalent S(1) atoms to form US6 octahedra that share corners with six equivalent Th(1)S6 octahedra, edges with six equivalent U(1)S6 octahedra, and edges with six equivalent Th(1)S6 octahedra. The corner-sharing octahedral tilt angles are 1°. Th(1) is bonded to six equivalent S(1) atoms to form ThS6 octahedra that share corners with six equivalent U(1)S6 octahedra, edges with six equivalent U(1)S6 octahedra, and edges with six equivalent Th(1)S6 octahedra. The corner-sharing octahedral tilt angles are 1°. S(1) is bonded to three equivalent U(1) and three equivalent Th(1) atoms to form a mixture of corner and edge-sharing STh3U3 octahedra. The corner-sharing octahedra are not tilted.
