MgSiO3 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 Si(1)O6 octahedra, edges with three equivalent Mg(1)O6 octahedra, and  a faceface with one Si(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-60°. Si(1) is bonded to six equivalent O(1) atoms to form SiO6 octahedra that share corners with nine equivalent Mg(1)O6 octahedra, edges with three equivalent Si(1)O6 octahedra, and  a faceface with one Mg(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 Mg(1) and two equivalent Si(1) atoms.
