Re Ir Ir Pb
ReIr2Pb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ReIr2Pb cluster. Re(1) is bonded in a distorted bent 120 degrees geometry to one Ir(2) and one Pb(1) atom. The Re(1)-Ir(2) bond length is 0.80 Å. The Re(1)-Pb(1) bond length is 0.93 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a distorted single-bond geometry to one Pb(1) atom. The Ir(1)-Pb(1) bond length is 1.76 Å. In the second Ir site, Ir(2) is bonded in a single-bond geometry to one Re(1) atom. Pb(1) is bonded in a distorted single-bond geometry to one Re(1) and one Ir(1) atom.
