The structure described by InSn2Te3 is Caswellsilverite-like structured and crystallizes in the trigonal P-3m1 space group. In(1) is bonded to six equivalent Te(1) atoms to form InTe6 octahedra that share corners with six equivalent Sn(1)Te6 octahedra, edges with six equivalent In(1)Te6 octahedra, and edges with six equivalent Sn(1)Te6 octahedra. The corner-sharing octahedra are not tilted. Sn(1) is bonded to three equivalent Te(1) and three equivalent Te(2) atoms to form SnTe6 octahedra that share corners with three equivalent In(1)Te6 octahedra, corners with three equivalent Sn(1)Te6 octahedra, edges with three equivalent In(1)Te6 octahedra, and edges with nine equivalent Sn(1)Te6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to three equivalent In(1) and three equivalent Sn(1) atoms to form TeIn3Sn3 octahedra that share corners with three equivalent Te(1)In3Sn3 octahedra, corners with three equivalent Te(2)Sn6 octahedra, edges with three equivalent Te(2)Sn6 octahedra, and edges with nine equivalent Te(1)In3Sn3 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. In the second Te site, Te(2) is bonded to six equivalent Sn(1) atoms to form TeSn6 octahedra that share corners with six equivalent Te(1)In3Sn3 octahedra, edges with six equivalent Te(1)In3Sn3 octahedra, and edges with six equivalent Te(2)Sn6 octahedra. The corner-sharing octahedral tilt angles are 1°. is represented by the Crystallographic Information File (CIF) [CIF]
