Old ligands with new coordination chemistry: Linear trinuclear mixed oxidation state cobalt(III/II/III) complexes and their mononuclear “ligand” cobalt(III) complexes featuring 2-pyridyloximates

A family of novel linear, trinuclear mixed-valence CoIIICoIICoIII clusters have been synthesised employing 2-pyridyloximato ligands; the mononuclear “ligand” CoIII units of the trinuclear clusters have also been prepared and characterised.
