Materials Data on YHg2 by Materials Project
YHg2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Y is bonded to twelve equivalent Hg atoms to form a mixture of distorted edge and face-sharing YHg12 cuboctahedra. All Y–Hg bond lengths are 3.35 Å. Hg is bonded in a 9-coordinate geometry to six equivalent Y and three equivalent Hg atoms. All Hg–Hg bond lengths are 2.87 Å.
