Ge Ir Pb Pb
IrPb2Ge is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two IrPb2Ge clusters. Ir(1) is bonded in a single-bond geometry to one Pb(2) and one Ge(1) atom. The Ir(1)-Pb(2) bond length is 2.28 Å. The Ir(1)-Ge(1) bond length is 0.54 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted single-bond geometry to one Ge(1) atom. The Pb(1)-Ge(1) bond length is 1.93 Å. In the second Pb site, Pb(2) is bonded in a distorted single-bond geometry to one Ir(1) atom. Ge(1) is bonded in a distorted single-bond geometry to one Ir(1) and one Pb(1) atom.
