NaMgHg2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two NaMgHg2 ribbons oriented in the (1, 0, 0) direction. Na is bonded in a linear geometry to two equivalent Hg atoms. Both Na–Hg bond lengths are 3.02 Å. Mg is bonded in a linear geometry to two equivalent Hg atoms. Both Mg–Hg bond lengths are 3.01 Å. Hg is bonded in a linear geometry to one Na and one Mg atom.
NaMgHg2 is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Na is bonded in a body-centered cubic geometry to eight equivalent Hg atoms. All Na–Hg bond lengths are 3.11 Å. Mg is bonded in a body-centered cubic geometry to eight equivalent Hg atoms. All Mg–Hg bond lengths are 3.11 Å. Hg is bonded in a body-centered cubic geometry to four equivalent Na and four equivalent Mg atoms.
