Abstract
The magnetic and EPR properties of the nitroxyl complex bis(di-tert-butyl nitroxide)cobalt(II) bromide have been reexamined. It is concluded that the ground state is a spin doublet, as shown by the magnetic susceptibility and the EPR spectra at liquid-helium temperature. The g values, which show large deviations from the free-electron value, are rationalized in terms of a sum of contributions from the radicals and the high-spin cobalt(I1) ion.File | Dimensione | Formato | |
