MnGeO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. Mn(1) is bonded to six equivalent O(1) atoms to form distorted MnO6 octahedra that share corners with nine equivalent Ge(1)O6 octahedra, edges with three equivalent Mn(1)O6 octahedra, and  a faceface with one Ge(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-60°. Ge(1) is bonded to six equivalent O(1) atoms to form GeO6 octahedra that share corners with nine equivalent Mn(1)O6 octahedra, edges with three equivalent Ge(1)O6 octahedra, and  a faceface with one Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-60°. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Mn(1) and two equivalent Ge(1) atoms.
