Nickel biomimic : A pentadentate ligand, 2,6‐bis((( S )‐2‐(diphenylhydroxymethyl)‐1‐pyrrolidinyl)methyl)pyridine (H 2 BDPP), was deprotonated and subsequently reacted with [Ni(CH 3 CN) 6 ](ClO 4 ) 2 to give Ni(BDPP) ( 1 ). A square‐pyramidal Ni III complex, [Ni(BDPP)](PF 6 ) ( 2 ), was obtained via oxidation of 1 . Complex 2 can oxidize O 2 − into O 2 and its EPR spectrum is similar to that of the oxidized form of NiSOD.
