Реферат:
New nitronyl nitroxide radicals, 2-(4′(5′)-methylimidazol-2′-yl)- and 2-(4′(5′)-trifluoromethylimidazol-2′-yl)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazole-1-oxyl 3-oxide, were synthesized. The molecular and crystal structures of the paramagnetic trifluoromethyl derivative were determined. A previously unknown type of hydrogen bonding of imidazol-2-yl-substituted nitronyl nitroxides to form ribbons was established. Within the ribbons, the molecules face in the same direction, with all oxygen atoms of the paramagnetic moieties being involved in H-bonding. The spectral and electrochemical properties of the radicals were compared. The first quantum chemical calculations of the electronic spectra of nitronyl nitroxide radicals taking account of the vibrational structure were performed.
