FeTiO3 is Ilmenite-like structured and crystallizes in the trigonal R3c space group. Ti(1) is bonded to six equivalent O(1) atoms to form TiO6 octahedra that share corners with three equivalent Fe(1)O6 octahedra, corners with six equivalent Ti(1)O6 octahedra, edges with three equivalent Fe(1)O6 octahedra, and  a faceface with one Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-59°. Fe(1) is bonded to six equivalent O(1) atoms to form FeO6 octahedra that share corners with three equivalent Ti(1)O6 octahedra, corners with six equivalent Fe(1)O6 octahedra, edges with three equivalent Ti(1)O6 octahedra, and  a faceface with one Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 53-59°. O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ti(1) and two equivalent Fe(1) atoms.
