Simple oxidative treatment is shown to activate metal carbonyl clusters by creating open sites to affect a 100­–fold catalytic rate enhancement of C2H4 hydrogenation.  Use of bulky organic ligands, which are significantly larger than the metal core, results in an open cluster catalyst that is stable during catalysis after oxidative treatment.
