Ac3Hg crystallizes in the hexagonal P6_3/mmc space group. Ac(1) is bonded in a 4-coordinate geometry to four equivalent Hg(1) atoms. Hg(1) is bonded to twelve equivalent Ac(1) atoms to form a mixture of corner and face-sharing HgAc12 cuboctahedra.
Ac3Hg crystallizes in the hexagonal P6_3/mmc space group. Ac(1) is bonded in a 4-coordinate geometry to four equivalent Hg(1) atoms. There are two shorter (3.63 Å) and two longer (3.85 Å) Ac(1)-Hg(1) bond lengths. Hg(1) is bonded to twelve equivalent Ac(1) atoms to form a mixture of corner and face-sharing HgAc12 cuboctahedra.
