Different states of O2 reduction found at the TNC of the Tth-MCO composite structures. (a) Tth-MCO-C1 in the O2 state. (b) Tth-MCO-C2 in the RS. (c) Tth-MCO-C6 in the FR state. Note that the O2 (red cylinder) is bridging the binuclear T3Cu–T3′Cu cluster at a dose of 0.2 MGy (12.5% dose) in (a), as well as the different occupancy values related to the radiation damage of both Cu atoms. The 2F o − F c electron-density map contoured at the 1σ level is drawn in blue. Metal ions are represented as spheres. Distances are in Å.
