Mg Co Pb Pb
MgCoPb2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgCoPb2 cluster. Mg(1) is bonded in a single-bond geometry to one Pb(1) atom. The Mg(1)-Pb(1) bond length is 2.02 Å. Co(1) is bonded in a bent 120 degrees geometry to one Pb(1) and one Pb(2) atom. The Co(1)-Pb(1) bond length is 1.28 Å. The Co(1)-Pb(2) bond length is 1.28 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted bent 120 degrees geometry to one Mg(1) and one Co(1) atom. In the second Pb site, Pb(2) is bonded in a single-bond geometry to one Co(1) atom.
