MgPtPb is Cyanogen Chloride-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgPtPb cluster. Mg(1) is bonded in a single-bond geometry to one Pb(1) atom. The Mg(1)-Pb(1) bond length is 1.03 Å. Pt(1) is bonded in a single-bond geometry to one Pb(1) atom. The Pt(1)-Pb(1) bond length is 0.11 Å. Pb(1) is bonded in a linear geometry to one Mg(1) and one Pt(1) atom.
