Ir Pb Pb W
WIrPb2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WIrPb2 clusters. W(1) is bonded in a single-bond geometry to one Pb(1) atom. The W(1)-Pb(1) bond length is 2.10 Å. Ir(1) is bonded in a linear geometry to one Pb(1) and one Pb(2) atom. The Ir(1)-Pb(1) bond length is 0.50 Å. The Ir(1)-Pb(2) bond length is 0.50 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a single-bond geometry to one W(1) and one Ir(1) atom. In the second Pb site, Pb(2) is bonded in a single-bond geometry to one Ir(1) atom.
