A six‐membered Co 2 O 4 ring in a chair conformation is featured in the diamagnetic dimer 2 , which is in equilibrium with its Co II monomer 1 (Δ H = ‐14.5(5) kcalmol −1 and Δ S = ‐60(3) cal (K −1 mol −1 ). The dimerization of 1 and loss of O 2 from 2 are steps en route to dioxygen activation. Tp′ = hydrotris(3‐isopropyl‐5‐methylpyrazolyl)borate).
