Materials Data on Rb4SbO4 by Materials Project

Abstract

Rb4SbO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Rb sites. In the first Rb site, Rb is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Rb–O bond distances ranging from 2.97–3.13 Å. In the second Rb site, Rb is bonded to four O atoms to form distorted RbO4 trigonal pyramids that share corners with four equivalent SbO4 tetrahedra and an edgeedge with one RbO4 trigonal pyramid. There are a spread of Rb–O bond distances ranging from 2.80–2.92 Å. In the third Rb site, Rb is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Rb–O bond distances ranging from 2.82–3.40 Å. In the fourth Rb site, Rb is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Rb–O bond distances ranging from 2.92–3.54 Å. Sb is bonded to four O atoms to form SbO4 tetrahedra that share corners with four equivalent RbO4 trigonal pyramids. There are a spread of Sb–O bond distances ranging from 1.96–2.03 Å. There are four inequivalent O sites. In the first O site, O is bonded in a 6-coordinate geometry to five Rb and one Sb atom. In the second O site, O is bonded in a 6-coordinate geometry to five Rb and one Sb atom. In the third O site, O is bonded in a 5-coordinate geometry to five Rb and one Sb atom. In the fourth O site, O is bonded in a 6-coordinate geometry to five Rb and one Sb atom.
