Materials Data on RbPb by Materials Project
RbPb crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. there are two inequivalent Rb sites. In the first Rb site, Rb is bonded in a 12-coordinate geometry to eight equivalent Pb atoms. There are a spread of Rb–Pb bond distances ranging from 4.02–4.08 Å. In the second Rb site, Rb is bonded in a 6-coordinate geometry to six equivalent Pb atoms. There are a spread of Rb–Pb bond distances ranging from 3.92–4.06 Å. Pb is bonded in a 10-coordinate geometry to seven Rb and three equivalent Pb atoms. There are one shorter (3.15 Å) and two longer (3.17 Å) Pb–Pb bond lengths.
