A record Co36 cluster is prepared. This mixed-valent compound containing CoII and CoIII centers is formed in the reaction of a dinuclear cobalt pivalate species with the polydentate 2,3-dicarboxypyrazine ligand. In terms of magnetic properties it behaves as a {Co16–Co16} supramolecular dimer in which the S=4 spin ground states of each monomer do not interact.
