The crystal structure described by (Hg)3C crystallizes in the tetragonal I4/mmm space group. The structure consists of two 02329_fluka atoms inside a Hg framework. In the Hg framework, there are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 8-coordinate geometry to four equivalent Hg(1) and four equivalent Hg(2) atoms. In the second Hg site, Hg(2) is bonded in a 8-coordinate geometry to eight equivalent Hg(1) atoms. is represented by the CIF card [CIF]
