Title: Materials Data on CsTi3AlO8 by Materials Project

Abstract

CsTi3AlO8 crystallizes in the triclinic P1 space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cs–O bond distances ranging from 3.02–3.14 Å. There are three inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four TiO6 octahedra, edges with two equivalent TiO6 octahedra, and edges with two equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 43–55°. There are a spread of Ti–O bond distances ranging from 1.91–2.11 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with two equivalent AlO6 octahedra, and edges with four TiO6 octahedra. The corner-sharing octahedra tilt angles range from 47–55°. There are a spread of Ti–O bond distances ranging from 1.88–2.10 Å. In the third Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with two equivalent AlO6 octahedra, and edges with four TiO6 octahedra. The corner-sharing octahedra tilt angles range from 43–55°. There are amore » spread of Ti–O bond distances ranging from 1.90–2.11 Å. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with four TiO6 octahedra, edges with two equivalent TiO6 octahedra, and edges with two equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 46–53°. There are a spread of Al–O bond distances ranging from 1.89–2.00 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to three Ti4+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ti4+ and two equivalent Al3+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ti4+ and one Al3+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ti4+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cs1+, two equivalent Ti4+, and one Al3+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cs1+, one Ti4+, and two equivalent Al3+ atoms. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cs1+ and three Ti4+ atoms. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cs1+ and three Ti4+ atoms.« less
