Materials Data on YPb2 by Materials Project
YPb2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Y is bonded in a 10-coordinate geometry to ten Pb atoms. There are a spread of Y–Pb bond distances ranging from 3.29–3.64 Å. There are two inequivalent Pb sites. In the first Pb site, Pb is bonded in a 4-coordinate geometry to six equivalent Y and two equivalent Pb atoms. Both Pb–Pb bond lengths are 3.27 Å. In the second Pb site, Pb is bonded in a 8-coordinate geometry to four equivalent Y and four equivalent Pb atoms. All Pb–Pb bond lengths are 3.25 Å.
