Abstract

NaFeTiO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.27–2.69 Å. 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 19–51°. There are a spread of Ti–O bond distances ranging from 1.88–2.12 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 19–51°. There are a spread of Fe–O bond distances ranging from 1.93–1.97 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Ti4+, and two equivalent Fe3+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Na1+ and two equivalent Ti4+ atoms. In the third O2- site, O2- is bonded to one Ti4+ andmore »« less
