Hg3Si crystallizes in the hexagonal P6_3/mmc space group. Hg(1) is bonded in a 6-coordinate geometry to four equivalent Hg(1) and two equivalent Si(1) atoms. Si(1) is bonded to six equivalent Hg(1) atoms to form distorted face-sharing SiHg6 pentagonal pyramids.
Hg3Si crystallizes in the hexagonal P6_3/mmc space group. Hg(1) is bonded in a 6-coordinate geometry to four equivalent Hg(1) and two equivalent Si(1) atoms. All Hg(1)-Hg(1) bond lengths are 3.09 Å. Both Hg(1)-Si(1) bond lengths are 2.83 Å. Si(1) is bonded to six equivalent Hg(1) atoms to form distorted face-sharing SiHg6 pentagonal pyramids.
