UThS2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. U(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form US6 octahedra that share corners with six equivalent U(1)S6 octahedra, edges with four equivalent U(1)S6 octahedra, and edges with eight equivalent Th(1)S6 octahedra. The corner-sharing octahedra are not tilted. Th(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form ThS6 octahedra that share corners with six equivalent Th(1)S6 octahedra, edges with four equivalent Th(1)S6 octahedra, and edges with eight equivalent U(1)S6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent S sites. In the first S site, S(1) is bonded to four equivalent U(1) and two equivalent Th(1) atoms to form STh2U4 octahedra that share corners with six equivalent S(1)Th2U4 octahedra, edges with four equivalent S(1)Th2U4 octahedra, and edges with eight equivalent S(2)Th4U2 octahedra. The corner-sharing octahedra are not tilted. In the second S site, S(2) is bonded to two equivalent U(1) and four equivalent Th(1) atoms to form STh4U2 octahedra that share corners with six equivalent S(2)Th4U2 octahedra, edges with four equivalent S(2)Th4U2 octahedra, and edges with eight equivalent S(1)Th2U4 octahedra. The corner-sharing octahedra are not tilted.
