Materials Data on Cs3LiPb4 by Materials Project

Abstract

Cs3LiPb4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Cs sites. In the first Cs site, Cs is bonded in a 2-coordinate geometry to eight Pb atoms. There are a spread of Cs–Pb bond distances ranging from 4.06–4.45 Å. In the second Cs site, Cs is bonded in a 1-coordinate geometry to seven Pb atoms. There are a spread of Cs–Pb bond distances ranging from 3.89–4.21 Å. Li is bonded in a distorted hexagonal planar geometry to six Pb atoms. There are two shorter (3.16 Å) and four longer (3.26 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 five Cs, two equivalent Li, and three Pb atoms. There are two shorter (3.14 Å) and one longer (3.25 Å) Pb–Pb bond lengths. In the second Pb site, Pb is bonded in a 10-coordinate geometry to six Cs, one Li, and three Pb atoms. The Pb–Pb bond length is 3.10 Å.
