YHg3 crystallizes in the hexagonal P6_3/mmc space group. Y(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of face and corner-sharing YHg12 cuboctahedra. Hg(1) is bonded in a 4-coordinate geometry to four equivalent Y(1) atoms.
YHg3 crystallizes in the hexagonal P6_3/mmc space group. Y(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of face and corner-sharing YHg12 cuboctahedra. There are six shorter (3.14 Å) and six longer (3.31 Å) Y(1)-Hg(1) bond lengths. Hg(1) is bonded in a 4-coordinate geometry to four equivalent Y(1) atoms.
