Self-assembly by ligand disassembly?--Formation of an unusual dodecanuclear [Co(II)6Co(III)6] cluster.
A sterically encumbered 'tritopic' picolinic-dihydrazone ligand reacts with cobalt(ii) nitrate in air to give a dodecanuclear [Co(ii)(6)Co(iii)(6)] cluster, in which six ligands are hydrolyzed to mono-carboxylate analogues.
