The redox non-innocent ligand bis(o-aminophenol) N,N '-bis(3,5-di-tertbutyl-2-hydroxy-phenyl)-1,2-phenyl-enediamine, H4L, reacts with CoCl2.6H2O in a methanol solution under aerobic conditions to form [Co(HL)2]. Both bis(o-aminophenol) ligands coordinate as tridentate and the ligand set can be described as a resonance structure of two partially oxidized ligands, while the formal oxidation state of the metal centre appears as + III. In this resonance structure, one ligand carries an odd electron, which makes the Co(III) complex paramagnetic.
