MnSnTe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Mn(1) is bonded to six equivalent Te(1) atoms to form MnTe6 octahedra that share corners with six equivalent Sn(1)Te6 octahedra, edges with six equivalent Mn(1)Te6 octahedra, and edges with six equivalent Sn(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 14°. Sn(1) is bonded to six equivalent Te(1) atoms to form SnTe6 octahedra that share corners with six equivalent Mn(1)Te6 octahedra, edges with six equivalent Mn(1)Te6 octahedra, and edges with six equivalent Sn(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 14°. Te(1) is bonded in a 6-coordinate geometry to three equivalent Mn(1) and three equivalent Sn(1) atoms.
