The compound described by Pb crystallizes in the tetragonal P4_2/mbc space group. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 5-coordinate geometry to one Pb(1) and four equivalent Pb(2) atoms. In the second Pb site, Pb(2) is bonded in a 8-coordinate geometry to eight equivalent Pb(1) atoms. is represented by the CIF card [CIF]
