MgHg5 crystallizes in the hexagonal P-62m space group. Mg(1) is bonded in a 6-coordinate geometry to six equivalent Hg(1) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a distorted water-like geometry to two equivalent Mg(1) and four equivalent Hg(2) atoms. In the second Hg site, Hg(2) is bonded in a 6-coordinate geometry to six equivalent Hg(1) atoms.
