Mn2CdTe3 is Caswellsilverite-like structured and crystallizes in the trigonal P-3m1 space group. Mn(1) is bonded to three equivalent Te(1) and three equivalent Te(2) atoms to form MnTe6 octahedra that share corners with three equivalent Mn(1)Te6 octahedra, corners with three equivalent Cd(1)Te6 octahedra, edges with three equivalent Cd(1)Te6 octahedra, and edges with nine equivalent Mn(1)Te6 octahedra. The corner-sharing octahedral tilt angles range from 0-7°. Cd(1) is bonded to six equivalent Te(2) atoms to form CdTe6 octahedra that share corners with six equivalent Mn(1)Te6 octahedra, edges with six equivalent Mn(1)Te6 octahedra, and edges with six equivalent Cd(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 7°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to six equivalent Mn(1) atoms to form TeMn6 octahedra that share corners with six equivalent Te(2)Mn3Cd3 octahedra, edges with six equivalent Te(2)Mn3Cd3 octahedra, and edges with six equivalent Te(1)Mn6 octahedra. The corner-sharing octahedral tilt angles are 2°. In the second Te site, Te(2) is bonded to three equivalent Mn(1) and three equivalent Cd(1) atoms to form TeMn3Cd3 octahedra that share corners with three equivalent Te(2)Mn3Cd3 octahedra, corners with three equivalent Te(1)Mn6 octahedra, edges with three equivalent Te(1)Mn6 octahedra, and edges with nine equivalent Te(2)Mn3Cd3 octahedra. The corner-sharing octahedral tilt angles range from 0-2°.
