Title: Materials Data on RbNbSiO5 by Materials Project

Abstract

RbNbSiO5 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 5-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 3.08–3.52 Å. In the second Rb1+ site, Rb1+ is bonded in a 3-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.93–3.58 Å. In the third 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 3.01–3.45 Å. There are three inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 38–43°. There are a spread of Nb–O bond distances ranging from 1.93–2.09 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with three NbO6 octahedra and corners with three SiO4 tetrahedra.

In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+ and two Nb5+ atoms. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to three Rb1+, one Nb5+, and one Si4+ atom.

In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+, one Nb5+, and one Si4+ atom. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Nb5+, and one Si4+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to three Rb1+ and two equivalent Nb5+ atoms. In the eleventh O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Nb5+, and one Si4+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Rb1+ and two Si4+ atoms. In the thirteenth O2- site, O2- is bonded in a distorted linear geometry to one Rb1+, one Nb5+, and one Si4+ atom. In the fourteenth O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+ and two Si4+ atoms. In the fifteenth O2- site, O2- is bonded in a 2-coordinate geometry to three Rb1+ and two Nb5+ atoms.« less
