Hg3Si crystallizes in the hexagonal P6_3/mmc space group. Hg(1) is bonded in a 8-coordinate geometry to six equivalent Hg(1) and two equivalent Si(1) atoms. Si(1) is bonded in a 6-coordinate geometry to six equivalent Hg(1) atoms.
Hg3Si crystallizes in the hexagonal P6_3/mmc space group. Hg(1) is bonded in a 8-coordinate geometry to six equivalent Hg(1) and two equivalent Si(1) atoms. There are four shorter (3.11 Å) and two longer (3.30 Å) Hg(1)-Hg(1) bond lengths. Both Hg(1)-Si(1) bond lengths are 2.95 Å. Si(1) is bonded in a 6-coordinate geometry to six equivalent Hg(1) atoms.
