Rajesh published the artcileManganese complexes of bis-benzimidazolyl ligand as novel quenchers of superoxide radical anion, Category: catalysis-chemistry, the publication is Polyhedron (1997), 16(20), 3511-3517, database is CAplus.
MnII/MnIII complexes [Mn(DGB)X2]0/+ and [Mn(BBB)2X]2+ were synthesized utilizing an exogenous anionic ligand (X = OAc, SCN) with tridentate bis(2-benzimidazolylmethyl)ether (DGB) and bidentate 1,2-bis(2-benzimidazolyloxamethyl)benzene (BBB) ligands. The visible spectra of the MnIII compounds suggests pseudo C4v symmetry, and the EPR data on the MnII complexes indicates a similar geometry. Cyclic-voltammetric studies reveal that the E1/2 for the MnII/MnIII couple shifts to a pos. value with acetate as an anionic ligand, implying that this anion stabilizes the MnII oxidation state while the E1/2 data for SCN reveals that the anion stabilizes the MnIII state. The reoxidation step of the superoxide formed in the cyclic-voltammetric experiments becomes irreversible in the presence of Mn complexes; suggesting that these complexes act as good quenchers for superoxide anion.
