mp-19417: TiFeO3 (trigonal, R-3, 148) - Materials Project

FeTiO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ti4+ is bonded to six equivalent O2- atoms to form distorted TiO6 octahedra that share corners with nine equivalent FeO6 octahedra, edges with three equivalent TiO6 octahedra, and a faceface with one FeO6 octahedra. The corner-sharing octahedra tilt angles range from 44–60°.
