Nb Ir Pb Pb
PbNb1IrPb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one IrPb cluster and one PbNb1 cluster. In the IrPb cluster, Ir(1) is bonded in a single-bond geometry to one Pb(1) atom. The Ir(1)-Pb(1) bond length is 0.43 Å. Pb(1) is bonded in a single-bond geometry to one Ir(1) atom. In the PbNb1 cluster, Nb(1) is bonded in a distorted single-bond geometry to one Pb(2) atom. The Nb(1)-Pb(2) bond length is 0.95 Å. Pb(2) is bonded in a single-bond geometry to one Nb(1) atom.
