Mg Mo Pb Pb
MgMoPb2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgMoPb2 cluster. Mg(1) is bonded in a distorted single-bond geometry to one Mo(1), one Pb(1), and one Pb(2) atom. The Mg(1)-Mo(1) bond length is 1.42 Å. The Mg(1)-Pb(1) bond length is 2.09 Å. The Mg(1)-Pb(2) bond length is 2.07 Å. Mo(1) is bonded in a distorted single-bond geometry to one Mg(1) and one Pb(1) atom. The Mo(1)-Pb(1) bond length is 2.07 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 3-coordinate geometry to one Mg(1), one Mo(1), and one Pb(2) atom. The Pb(1)-Pb(2) bond length is 1.42 Å. In the second Pb site, Pb(2) is bonded in a 2-coordinate geometry to one Mg(1) and one Pb(1) atom.
