| dc.description.abstract | The mononuclear [CuII(HL)2] (1) and dinuclear [MnIII2(μ1,3-OAc)2L2] (2) [H2L = N-(2-hydroxypropyl)-3-methoxysalicylaldimine] compounds have been synthesized and characterized using microanalytical, spectroscopic and X-ray crystallographic results. Structural analysis reveals a bidentate chelation behavior of the monoanionic HL ligand, having a distorted square planar coordination environment around copper(II) with a CuN2O2 chromophore. In compound 2, each manganese(III) center has a distorted octahedral geometry, with an MnN2O4 chromophore bridged by two acetate ligands in a μ1,3 fashion. Variable-temperature magnetic susceptibility measurements of 2 indicate an antiferromagnetic interaction between the two manganese(III) centers. Both 1 and 2 behave as effective catalysts towards the oxidation of 3,5-di-tert-butylcatechol to its corresponding quinone with molecular oxygen in methanolic solution. | en_US |
