Title: Materials Data on Ti3TlSi2P6O25 by Materials Project

Abstract

Ti3TlSi2P6O25 crystallizes in the trigonal P-31c space group. The structure is three-dimensional. there are two inequivalent Ti+3.67+ sites. In the first Ti+3.67+ site, Ti+3.67+ is bonded to six equivalent O2- atoms to form TiO6 octahedra that share corners with six equivalent PO4 tetrahedra. All Ti–O bond lengths are 1.97 Å. In the second Ti+3.67+ site, Ti+3.67+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent PO4 tetrahedra. There is three shorter (1.98 Å) and three longer (2.00 Å) Ti–O bond length. Tl1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Tl–O bond lengths are 3.17 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one SiO4 tetrahedra and corners with three equivalent PO4 tetrahedra. There is one shorter (1.60 Å) and three longer (1.63 Å) Si–O bond length. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three TiO6 octahedra and a cornercorner with one SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 26–41°. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. There are five inequivalent O2- sites. In themore » first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.67+ and one P5+ atom. In the second O2- site, O2- is bonded in a linear geometry to two equivalent Si4+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ti+3.67+, one Tl1+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Si4+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ti+3.67+ and one P5+ atom.« less
