The crystal structure described by Yb2Pb is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. In the second Yb site, Yb(2) is bonded to four equivalent Pb(1) atoms to form a mixture of distorted corner and edge-sharing YbPb4 trigonal pyramids. Pb(1) is bonded in a 7-coordinate geometry to four equivalent Yb(2) and five equivalent Yb(1) atoms. is represented by the CIF file [CIF]
