Abstract

Intramolecular ligand hydroxylation was observed during the reactions of dioxygen with the dicopper(I) complexes of the ligands L1 (L 1 = α,ά-bis[(2-pyridylethyl)amino]-m-xylene) and L3 (L3 = α,ά-bis[N-(2-pyridylethyl)-N- (2-pyridylmethyl)amino]-m-xylene). The dinuclear copper(I) complex [Cu 2L3](ClO4)2 (3) and the dicopper(II) complex [Cu2(L1-O)(OH)(ClO4)]ClO4 (1) were characterized by single-crystal X-ray structure analysis. Furthermore, phenolatebridged complexes were synthesized with the ligand L2-OH (structurally characterized [Cu2(L2-O)Cl3] (7) with L2 = α,ά-bis[N-methyl-N-(2-pyridylethyl) amino]-m-xylene; synthesized from the reaction between [Cu2(L 2-O)(OH)](ClO4)2 (2) and Cl-) and Me-L3-OH: [Cu2(Me-L3-O)(μ-X)](ClO 4)2·nH2O (Me-L3-OH = 2,6-bis[N-(2-pyridylethyl)-N-(2-pyridylmethyl)amino]-4-methylphenol and X = C3H3N2 - (prz) (4), MeCO 2 - (5) and N3 - (6)). The magnetochemical characteristics of compounds 4-7 were determined by temperature-dependent magnetic studies, revealing their antiferromagnetic behaviour [-2J(in cm-1) values: -92 for 4, -86 for 5 and -88 for 6; -374 for 7].
