LaHg3 crystallizes in the hexagonal P6_3/mmc space group. La(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of corner and face-sharing LaHg12 cuboctahedra. Hg(1) is bonded in a 4-coordinate geometry to four equivalent La(1) atoms.
LaHg3 crystallizes in the hexagonal P6_3/mmc space group. La(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of corner and face-sharing LaHg12 cuboctahedra. There are six shorter (3.26 Å) and six longer (3.46 Å) La(1)-Hg(1) bond lengths. Hg(1) is bonded in a 4-coordinate geometry to four equivalent La(1) atoms.
