Materials Data on Rb3LiPb4 by Materials Project

Abstract

Rb3LiPb4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Rb sites. In the first Rb site, Rb is bonded in a bent 150 degrees geometry to two equivalent Pb atoms. Both Rb–Pb bond lengths are 3.87 Å. In the second Rb site, Rb is bonded in a 1-coordinate geometry to seven Pb atoms. There are a spread of Rb–Pb bond distances ranging from 3.71–4.23 Å. Li is bonded in a distorted hexagonal planar geometry to six Pb atoms. There are two shorter (3.10 Å) and four longer (3.16 Å) Li–Pb bond lengths. There are two inequivalent Pb sites. In the first Pb site, Pb is bonded in a 2-coordinate geometry to four equivalent Rb and two equivalent Li atoms. In the second Pb site, Pb is bonded in a 3-coordinate geometry to four Rb and one Li atom.
