Materials Data on YbHg2 by Materials Project
YbHg2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Yb is bonded to twelve equivalent Hg atoms to form a mixture of edge and face-sharing YbHg12 cuboctahedra. All Yb–Hg bond lengths are 3.38 Å. Hg is bonded in a 9-coordinate geometry to six equivalent Yb and three equivalent Hg atoms. All Hg–Hg bond lengths are 2.87 Å.
