Materials Data on CsTiAlO4 by Materials Project
CsAlTiO4 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Cs–O bond lengths are 3.29 Å. In the second Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Cs–O bond lengths are 3.29 Å. Ti4+ is bonded to four O2- atoms to form TiO4 tetrahedra that share a cornercorner with one TiO4 tetrahedra and corners with three equivalent AlO4 tetrahedra. There are a spread of Ti–O bond distances ranging from 1.81–1.83 Å. Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share a cornercorner with one AlO4 tetrahedra and corners with three equivalent TiO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.72–1.79 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two Cs1+, one Ti4+, and one Al3+ atom. In the second O2- site, O2- is bonded in a linear geometry to one Ti4+ and one Al3+ atom. In the third O2- site, O2- is bonded in a linear geometry to two equivalent Al3+ atoms. In the fourth O2- site, O2- is bonded in a linear geometry to two equivalent Ti4+ atoms.
