The structure described by MnGeTe2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Mn(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form MnTe6 octahedra that share corners with six equivalent Mn(1)Te6 octahedra, edges with four equivalent Mn(1)Te6 octahedra, and edges with eight equivalent Ge(1)Te6 octahedra. The corner-sharing octahedra are not tilted. Ge(1) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form GeTe6 octahedra that share corners with six equivalent Ge(1)Te6 octahedra, edges with four equivalent Ge(1)Te6 octahedra, and edges with eight equivalent Mn(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 four equivalent Mn(1) and two equivalent Ge(1) atoms to form TeMn4Ge2 octahedra that share corners with six equivalent Te(1)Mn4Ge2 octahedra, edges with four equivalent Te(1)Mn4Ge2 octahedra, and edges with eight equivalent Te(2)Mn2Ge4 octahedra. The corner-sharing octahedra are not tilted. In the second Te site, Te(2) is bonded to two equivalent Mn(1) and four equivalent Ge(1) atoms to form TeMn2Ge4 octahedra that share corners with six equivalent Te(2)Mn2Ge4 octahedra, edges with four equivalent Te(2)Mn2Ge4 octahedra, and edges with eight equivalent Te(1)Mn4Ge2 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
