TlInS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Tl(1) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. In(1) is bonded to six equivalent S(1) atoms to form edge-sharing InS6 octahedra. S(1) is bonded to three equivalent Tl(1) and three equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing STl3In3 octahedra. The corner-sharing octahedra are not tilted.
