摘要：

Reacting the heptadentate ligand 2,2'-(((pyridine-2,6-diylbis(methylene))bis((pyridin-2-ylmethyl)-azanediyl))bis(methylene))diphenol (H2L) with one equivalent of CuCl2 center dot 6H(2)O, NiCl2 center dot 6H(2)O and FeCl3 center dot 6H(2)O, followed by anion exchange with PF6-, BPh4- and ClO4- formed three mononuclear complexes [Cu(H2L)](Cl)(PF6) (1), [Ni(HL)](BPh4) (2) and [Fe(L)](ClO4) (3), respectively. Their structures in the solid state were determined by X-ray crystallography. The three metal centers in complexes 1-3 adopt distorted tetragonal pyramidal (Cu2+), octahedral (Ni2+) and pentagonal bipyramidal (Fe3+) geometries, respectively. In addition, the electrochemistry and their catalytic activity in the oxidation reaction of benzene to phenol by H2O2 were investigated. (C) 2014 Elsevier Ltd. All rights reserved.
