Na Na Cd Pb
Na2CdPb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Na2CdPb cluster. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a single-bond geometry to one Pb(1) atom. The Na(1)-Pb(1) bond length is 1.36 Å. In the second Na site, Na(2) is bonded in a distorted single-bond geometry to one Cd(1) atom. The Na(2)-Cd(1) bond length is 1.00 Å. Cd(1) is bonded in a distorted linear geometry to one Na(2) and one Pb(1) atom. The Cd(1)-Pb(1) bond length is 2.13 Å. Pb(1) is bonded in a distorted bent 150 degrees geometry to one Na(1) and one Cd(1) atom.
