Kurzfassung englisch:
New bi- and trinuclear copper(II) complexes of aroylhydrazones of TFA and benzencarboxylic acids were synthesized and characterized. Despite long range intramolecular Cu...Cu distances of about 10 Å, exchange coupling between paramagnetic centres are observed with J values of 0.33 and 0.37 cm-1 in binuclear complexes, and - 0.33 cm-1 in trinuclear complex. Seven hyperfine peaks with a value of aCu = 37.0⋅10-4 cm-1 are observed in EPR spectra of binuclear complexes. The possible mechanisms responsible for the observed weak long range coupling via aromatic spacer are discussed.
