The crystal structure described by YbMgPb crystallizes in the hexagonal P-62m space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted trigonal planar geometry to six equivalent Yb(1) and three equivalent Pb(1) atoms. In the second Mg site, Mg(2) is bonded in a 9-coordinate geometry to three equivalent Yb(1) and six equivalent Pb(1) atoms. Yb(1) is bonded in a 11-coordinate geometry to one Mg(2), four equivalent Mg(1), and six equivalent Pb(1) atoms. Pb(1) is bonded in a 10-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), and six equivalent Yb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
