The material structure described by MgGeO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. Mg(1) is bonded to six equivalent O(1) atoms to form distorted MgO6 octahedra that share corners with nine equivalent Ge(1)O6 octahedra, edges with three equivalent Mg(1)O6 octahedra, and  a faceface with one Ge(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-61°.

The corner-sharing octahedral tilt angles range from 42-61°. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Mg(1) and two equivalent Ge(1) atoms. is represented by the CIF file [CIF]
