Abstract

Nickel biomimic: A pentadentate ligand, 2,6-bis(((S)-2- (diphenylhydroxymethyl)-1-pyrrolidinyl)methyl)pyridine (H2BDPP), was deprotonated and subsequently reacted with [Ni(CH3CN) 6](ClO4)2 to give Ni(BDPP) (1). A square-pyramidal NiIII complex, [Ni(BDPP)](PF6) (2), was obtained via oxidation of 1. Complex 2 can oxidize O2- into O2 and its EPR spectrum is similar to that of the oxidized form of NiSOD.
