Abstract
[Ir4(C0)12o] n the surface of MgO reacts to give [HIr4(CO)ll]-,w hich upon treatment with co at 200 OC gives [Ir6(C0)15]2-
on the surface in high yield. Treatment of the latter with a solution of [PPN][CI] leads to extraction of [Ir6(C0)15]2b-y
cation metathesis. The surface-bound [Ir6(CO)15]2w- as characterized by extended X-ray absorption fine
