ThHg3 crystallizes in the hexagonal P6_3/mmc space group. Th(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of face and corner-sharing ThHg12 cuboctahedra. Hg(1) is bonded in a 10-coordinate geometry to four equivalent Th(1) and six equivalent Hg(1) atoms.
ThHg3 crystallizes in the hexagonal P6_3/mmc space group. Th(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of face and corner-sharing ThHg12 cuboctahedra. There are six shorter (3.21 Å) and six longer (3.41 Å) Th(1)-Hg(1) bond lengths. Hg(1) is bonded in a 10-coordinate geometry to four equivalent Th(1) and six equivalent Hg(1) atoms. There are four shorter (3.13 Å) and two longer (3.30 Å) Hg(1)-Hg(1) bond lengths.
