Materials Data on RbTiP2O7 by Materials Project
RbTiP2O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.91–3.48 Å. Ti3+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Ti–O bond distances ranging from 1.97–2.12 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent TiO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 14–47°. There are a spread of P–O bond distances ranging from 1.52–1.63 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent TiO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 17–51°. There are a spread of P–O bond distances ranging from 1.52–1.64 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Ti3+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to one Rb1+, one Ti3+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Rb1+, one Ti3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted linear geometry to one Rb1+, one Ti3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Ti3+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Ti3+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Rb1+ and two P5+ atoms.
