Giant clusters : Metal‐assisted hydrolysis of 2,6‐bis(2‐pyridylcarbonyl)pyridine with Co(O 2 CMe) 2 ⋅4 H 2 O in hot DMF yielded an icosanuclear Co II complex containing the triply deprotonated bis( gem ‐diol) form of the ligand and exhibiting superparamagnetic relaxation of its magnetization. The picture shows the central Co–O core of the complex (Co violet, O red).
