Materials Data on YbHgPb by Materials Project

YbHgPb is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Yb is bonded to six equivalent Hg and six equivalent Pb atoms to form a mixture of face and edge-sharing YbHg6Pb6 cuboctahedra. All Yb–Hg bond lengths are 3.49 Å. All Yb–Pb bond lengths are 3.49 Å. Hg is bonded in a 9-coordinate geometry to six equivalent Yb and three equivalent Pb atoms. All Hg–Pb bond lengths are 2.96 Å. Pb is bonded in a 9-coordinate geometry to six equivalent Yb and three equivalent Hg atoms.
