Title: Materials Data on Rb2Ti2(PO4)3 by Materials Project

Abstract

Rb2Ti2(PO4)3 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.96–3.20 Å. In the second Rb1+ site, Rb1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Rb–O bond distances ranging from 2.92–3.26 Å. There are two inequivalent Ti+3.50+ sites. In the first Ti+3.50+ site, Ti+3.50+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent PO4 tetrahedra. All Ti–O bond lengths are 2.00 Å. In the second Ti+3.50+ site, Ti+3.50+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent PO4 tetrahedra. There are three shorter (2.01 Å) and three longer (2.03 Å) Ti–O bond lengths. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four TiO6 octahedra. The corner-sharing octahedra tilt angles range from 10–44°. All P–O bond lengths are 1.55 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linearmore » geometry to two Rb1+, one Ti+3.50+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+, one Ti+3.50+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to three Rb1+, one Ti+3.50+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Ti+3.50+, and one P5+ atom.« less
