A series of nitronyl and imino nitroxides: amides 2, 13 (NN-C(O)-NH 2, INC(O)NH 2), iminoethers 3a,b, 15 (NN-C(NH)-OR (R = CH 3, 2-Pr), IN-C(NH)-OCH 3), carboxylates 4, 14a-c (NN-C(O)-OK, IN-C(O)-OX (X = K +, ( n-Bu) 4N +)), and paramagnetic tetrazoles 5, 7-12 were synthesized from 2-cyano-4,4,5,5-tetramethyl-4,5-dihydro-1 H-imidazole-1-oxyl-3-oxide (NN-C N). The crystal and molecular structure was determined for all compounds except 4, 14c, and 15. Key words. Nitronyl nitroxide - imino nitroxide - structure - magnetic properties - molecular materials.
