YbHg2 crystallizes in the trigonal P-3m1 space group. Yb(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of face and edge-sharing YbHg12 cuboctahedra. Hg(1) is bonded in a 9-coordinate geometry to six equivalent Yb(1) and three equivalent Hg(1) atoms.
YbHg2 crystallizes in the trigonal P-3m1 space group. Yb(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of face and edge-sharing YbHg12 cuboctahedra. There are six shorter (3.31 Å) and six longer (3.33 Å) Yb(1)-Hg(1) bond lengths. Hg(1) is bonded in a 9-coordinate geometry to six equivalent Yb(1) and three equivalent Hg(1) atoms. All Hg(1)-Hg(1) bond lengths are 2.82 Å.
