The crystal structure described by Hg3Pb crystallizes in the hexagonal P6_3/mmc space group. Hg(1) is bonded in a 10-coordinate geometry to six equivalent Hg(1) and four equivalent Pb(1) atoms. Pb(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of corner and face-sharing PbHg12 cuboctahedra. is represented by the CIF file [CIF]
