Transition Metals with Imidazoline Nitroxides

Complexes of Transition Metals with Imidazoline Nitroxides 

For understanding the magnetic properties of the substance, it is important to investigate multispin systems and obtain information concerning the exchange interactions. Extensive investigations of this kind are carried out for clusters of paramagnetic metals. 

The first detailed study of the ESR spectra of transition metal complexes with stable radicals was carried out as part of a study (Sagdeev 

Parameters of the ESR spectra of the investigated complexes are given in Table II. In the spectrum of the copper-complex solution one 

There are no detectable absorption signals for the complex NiL2 at room temperature or at liquid nitrogen temperatures.

Many derivatives of imidazoline nitroxides proved to be capable of chelation without involvement of the radical center. Complexes with ions of transition metals were generated from carboxylic acids 107 and 108...
