The structure described by Hg crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 4-coordinate geometry to four equivalent Hg(2) atoms. In the second Hg site, Hg(2) is bonded in a 7-coordinate geometry to two equivalent Hg(1) and five equivalent Hg(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
