CuPb2Te is alpha Po structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CuPb2Te cluster. Cu(1) is bonded in a distorted L-shaped geometry to one Pb(1) and one Pb(2) atom. The Cu(1)-Pb(1) bond length is 1.61 Å. The Cu(1)-Pb(2) bond length is 1.74 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 2-coordinate geometry to one Cu(1) and one Te(1) atom. The Pb(1)-Te(1) bond length is 1.74 Å. In the second Pb site, Pb(2) is bonded in a distorted L-shaped geometry to one Cu(1) and one Te(1) atom. The Pb(2)-Te(1) bond length is 1.61 Å. Te(1) is bonded in a distorted L-shaped geometry to one Pb(1) and one Pb(2) atom.
