Materials Data on Na2CdPb by Materials Project

Abstract

Na2CdPb crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Na sites. In the first Na site, Na is bonded to four equivalent Pb atoms to form distorted corner-sharing NaPb4 tetrahedra. All Na–Pb bond lengths are 3.25 Å. In the second Na site, Na is bonded to four equivalent Cd atoms to form distorted corner-sharing NaCd4 tetrahedra. All Na–Cd bond lengths are 3.25 Å. Cd is bonded in a body-centered cubic geometry to four equivalent Na and four equivalent Pb atoms. All Cd–Pb bond lengths are 3.25 Å. Pb is bonded in a distorted body-centered cubic geometry to four equivalent Na and four equivalent Cd atoms.
