Title: Materials Data on Rb2Si3SnO9 by Materials Project

Abstract

Rb2SnSi3O9 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.98–3.25 Å. Sn4+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with six equivalent SiO4 tetrahedra. All Sn–O bond lengths are 2.07 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent SnO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 38°. There are a spread of Si–O bond distances ranging from 1.62–1.68 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Sn4+, and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Rb1+ and two equivalent Si4+ atoms.
