Abstract

We report the Xband 9 GHz electron paramagnetic resonance EPR study of series of bisosemiquinonatocopperII complexes with different ligands It was found previously that exchange interactions in spin triads of these compounds are very sensitive to the structure of the ligand coordinated to the central copperII ion Ligand moderates the copper–radical and radical–radical exchange interactions and strongly changes the magnetic properties of the compound Depending on a ligand ferromagnetic or antiferromagnetic character of exchange dominates in the system The EPR study of these complexes allowed us to obtain information on zerofield splitting parameters and their distributions in the studied compounds The EPR results compliment previously obtained spectroscopic data on these compounds and suggest the pronounced plasticity of the clusters manifested in the broad distributions of their rhombicity parametersWe are very thankful to Dr Galina V Romanenko International Topographic Center Novosibirsk Russia for fruitful discussions on the Xray structures of the studied complexes This work was supported by the Russian Foundation for Basic Research nr 080300326 the Council under the Russian Federation president MK6020083 the Alexander von Humboldt Foundation MF the Grant for the Leading Scientific Schools NSh360420083 the Russian Science Support Foundation and the Program of Presidium Russian Academy of Sciences nr 1813 Federal Agency for Science and Innovations No 02513123098 and Federal Agency for Education No P 1144
