摘要：

Giant clusters: Metal-assisted hydrolysis of 2,6-bis(2-pyridylcarbonyl) pyridine with Co(O2CMe)2·4H2O in hot DMF yielded an icosanuclear CoII 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). (Chemical Equation Presented). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
