Materials Data on Ti(FeO2)3 by Materials Project
Abstract
Ti(FeO2)3 is Ilmenite-like structured and crystallizes in the trigonal R3 space group. The structure is three-dimensional. Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share corners with nine FeO6 octahedra, edges with three equivalent FeO6 octahedra, and a faceface with one FeO6 octahedra. The corner-sharing octahedra tilt angles range from 49–57°. There are three shorter (1.92 Å) and three longer (2.09 Å) Ti–O bond lengths. There are three inequivalent Fe+2.67+ sites. In the first Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form distorted FeO6 octahedra that share corners with three equivalent FeO6 octahedra, corners with six equivalent TiO6 octahedra, edges with three equivalent FeO6 octahedra, and a faceface with one FeO6 octahedra. The corner-sharing octahedra tilt angles range from 49–64°. There are three shorter (2.08 Å) and three longer (2.25 Å) Fe–O bond lengths. In the second Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with three equivalent TiO6 octahedra, corners with six equivalent FeO6 octahedra, edges with three equivalent FeO6 octahedra, and a faceface with one TiO6 octahedra. The corner-sharing octahedra tilt angles range from 44–57°. There are three shorter (2.02 Å) andmore »

In the second O2- site, O2- is bonded in a distorted see-saw-like geometry to one Ti4+ and three Fe+2.67+ atoms.},
