Zusammenfassung: | Copyright © 2012 John Wiley & Sons, Ltd. The (1)H NMR spectra of semiquinalate cobalt complex have been analyzed in a wide range of temperatures. It has been established that the intramolecular exchange requires the obligatory presence of a paramagnetic structure containing non-compensated electron spin localized on the carbon atom of the ligand aromatic ring, the cobalt atom being trivalent. The presence of such a structure leads to the appearance of satellite signals in the NMR spectra because of the superfine interactions |
