Title: Materials Data on LiTiFeO4 by Materials Project

Abstract

LiFeTiO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded in a 3-coordinate geometry to three O2- atoms. There is one shorter (1.93 Å) and two longer (2.03 Å) Li–O bond length. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with three equivalent FeO6 octahedra, edges with two equivalent TiO6 octahedra, and edges with two equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 29–49°. There are a spread of Ti–O bond distances ranging from 1.91–2.14 Å. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with three equivalent TiO6 octahedra, edges with two equivalent TiO6 octahedra, and edges with four equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 29–49°. There are a spread of Fe–O bond distances ranging from 1.99–2.08 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to one Ti4+ and three equivalent Fe3+ atoms to form distorted OTiFe3 trigonal pyramids that share a cornercorner with one OLi2Ti2Fe square pyramid, corners with two equivalent OTiFe3 trigonal pyramids, edges with two equivalent OLi2Ti2Fe square pyramids, and edges with two equivalent OTiFe3 trigonal pyramids.more » In the second O2- site, O2- is bonded in a trigonal planar geometry to one Li1+ and two equivalent Ti4+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+ and two equivalent Fe3+ atoms. In the fourth O2- site, O2- is bonded to two equivalent Li1+, two equivalent Ti4+, and one Fe3+ atom to form distorted OLi2Ti2Fe square pyramids that share a cornercorner with one OTiFe3 trigonal pyramid, edges with two equivalent OLi2Ti2Fe square pyramids, and edges with two equivalent OTiFe3 trigonal pyramids.« less
