SbTe2 is Calaverite structured and crystallizes in the trigonal P-3m1 space group. Sb(1) is bonded to six equivalent Te(1) atoms to form SbTe6 octahedra that share corners with six equivalent Te(1)Sb3Te3 octahedra, edges with six equivalent Sb(1)Te6 octahedra, and edges with six equivalent Te(1)Sb3Te3 octahedra. The corner-sharing octahedral tilt angles are 7°. Te(1) is bonded to three equivalent Sb(1) and three equivalent Te(1) atoms to form distorted TeSb3Te3 octahedra that share corners with three equivalent Sb(1)Te6 octahedra, corners with three equivalent Te(1)Sb3Te3 octahedra, edges with three equivalent Sb(1)Te6 octahedra, and edges with nine equivalent Te(1)Sb3Te3 octahedra. The corner-sharing octahedral tilt angles range from 0-7°.
