Te Pb W W
W2PbTe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two W2PbTe clusters. W(1) is bonded in a 2-coordinate geometry to one Pb(1) and one Te(1) atom. The W(1)-Pb(1) bond length is 2.09 Å. The W(1)-Te(1) bond length is 2.09 Å. Pb(1) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms. Te(1) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms.
