Dicobalt octacarbonyl is the organometallic compound with composition Co 2 (CO) 8.This metal carbonyl is used as a reagent and catalyst in organometallic chemistry and organic synthesis, and is central to much known organocobalt chemistry. The authors describe the enhancement of the area-selective chemical vapor deposition of cobalt films on one oxide surface over another from the precursor Co 2 (CO) 8 by addition of the nucleation inhibitor ammonia (NH 3).In the absence of an NH 3 coflow, the Co 2 (CO) 8 precursor exhibits a weak intrinsic selectivity: at 70 °C, Co nucleates quickly on Al 2 O 3 but more slowly on SiO 2. We believe that the co‐adsorption of ozone and the subsequent oxidation of the cobalt nanoclusters to Co x O y is more likely than the low temperature oxidation of carbon monoxide.
