Photoelectron spectroscopic analysis and DFT calculations of two O‐rich tungsten oxide clusters [W 2 O 8 ] − and [W 3 O 11 ] − showed these anions are superoxide complexes [W 2 O 6 (O 2 − )] and [W 3 O 9 (O 2 − )]. The data suggest that the clusters [W 2 O 6 ] − and [W 3 O 9 ] − can activate O 2 through a one‐electron transfer to form superoxide, which makes them simple molecular models for the chemisorption of O 2 at reduced defect sites on tungsten oxide surfaces.
