The structure described by Mg3Au2Hg is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a body-centered cubic geometry to four equivalent Au(1) and four equivalent Hg(1) atoms. In the second Mg site, Mg(2) is bonded in a body-centered cubic geometry to eight equivalent Au(1) atoms. Au(1) is bonded in a body-centered cubic geometry to four equivalent Mg(1) and four equivalent Mg(2) atoms. Hg(1) is bonded in a body-centered cubic geometry to eight equivalent Mg(1) atoms. is represented by the CIF card [CIF]
