Materials Data on Rb3PbO3 by Materials Project

Abstract

Rb3PbO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Rb sites. In the first Rb site, Rb is bonded to four O atoms to form distorted RbO4 trigonal pyramids that share corners with five equivalent PbO4 tetrahedra and an edgeedge with one RbO4 trigonal pyramid. There are a spread of Rb–O bond distances ranging from 2.80–3.08 Å. In the second 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 2.90–3.43 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 2.73–3.30 Å. Pb is bonded to four O atoms to form PbO4 tetrahedra that share corners with five equivalent RbO4 trigonal pyramids and an edgeedge with one PbO4 tetrahedra. There are a spread of Pb–O bond distances ranging from 2.19–2.30 Å. There are three inequivalent O sites. In the first O site, O is bonded in a 7-coordinate geometry to six Rb and one Pb atom. In the second O site, O is bonded in a 6-coordinate geometry to four Rb and two equivalent Pb atoms. In the third O site, O is bonded in a 5-coordinate geometry to four Rb and one Pb atom.
