The material structure described by Mg3Pb is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded in a distorted see-saw-like geometry to four equivalent Pb(1) atoms. Pb(1) is bonded to twelve equivalent Mg(1) atoms to form a mixture of corner and face-sharing PbMg12 cuboctahedra. is represented by the CIF file [CIF]
