The structure described by MgHg2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a 10-coordinate geometry to four equivalent Hg(1) and six equivalent Hg(2) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) atoms. In the second Hg site, Hg(2) is bonded in a 6-coordinate geometry to six equivalent Mg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
