La Ir Ir
LaIr2 is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaIr2 clusters. La(1) is bonded in a linear geometry to one Ir(1) and one Ir(2) atom. The La(1)-Ir(1) bond length is 1.14 Å. The La(1)-Ir(2) bond length is 0.36 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a single-bond geometry to one La(1) atom. In the second Ir site, Ir(2) is bonded in a single-bond geometry to one La(1) atom.
