Detection of Electron Paramagnetic Resonance Signals from Three Different Isotope Combinations 63Cu/63Cu, 63Cu/65Cu and 65Cu/65Cu in Stable Dicopper(I) Radical Complexes

The new stable paramagnetic cations (1+), adcOR'' = azodicarboxylic ester, have been characterized by high-resolution EPR spectroscopy.Two equivalent copper centres within one molecule give rise to isotope combinations 63Cu/63Cu (47.9percent), 63Cu/65Cu (42.6percent) and 65Cu/65Cu (9.5percent); both isotopes have I = 3/2, but the nuclear magnetic moment is 7.1percent higher for 65Cu.A theoretical analysis of the hyperfine splitting pattern, including a stick spectrum and actual computer simulations, is given, and experimantal spectra could be sucessfully reproduced in this way.Factors favouring the detection of individual isotope combination lines, particularly in the outer special regions, are the small number of coupling nuclei (14N, 31P) in the ligands, the rather narrow EPR lines of these ligand-centred radical complexes and the relatively large isotropic copper coupling constants of ca. 1.6 mT.
