LiMgPb2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two LiMgPb2 ribbons oriented in the (1, 0, 0) direction. Li is bonded in a linear geometry to two equivalent Pb atoms. Both Li–Pb bond lengths are 2.78 Å. Mg is bonded in a linear geometry to two equivalent Pb atoms. Both Mg–Pb bond lengths are 2.83 Å. Pb is bonded in a linear geometry to one Li and one Mg atom.
LiMgPb2 is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Li is bonded in a body-centered cubic geometry to eight equivalent Pb atoms. All Li–Pb bond lengths are 3.21 Å. Mg is bonded in a body-centered cubic geometry to eight equivalent Pb atoms. All Mg–Pb bond lengths are 3.21 Å. Pb is bonded in a body-centered cubic geometry to four equivalent Li and four equivalent Mg atoms.
