HgY is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Y is bonded in a body-centered cubic geometry to eight equivalent Hg atoms. All Y–Hg bond lengths are 3.23 Å. Hg is bonded in a body-centered cubic geometry to eight equivalent Y atoms.
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.
YHg3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Y is bonded to twelve equivalent Hg atoms to form a mixture of corner and face-sharing YHg12 cuboctahedra. There are six shorter (3.17 Å) and six longer (3.33 Å) Y–Hg bond lengths. Hg is bonded in a 4-coordinate geometry to four equivalent Y atoms.
