Radical ion salts of aromatic N-oxides: IV. Salts formed by N-alkoxypyridinium cations and 7,7,8,8-tetracyanoquinodimethane radical anion

Twelve new complex radical ion salts formed by N-alkoxypyridinium cations a nd 7,7,8,8-tetra-cyanoquinodimethane radical anion were isolated and examin ed by IR, UV, ESR, and H-1 and C-13 NMR spectroscopy. Specific resistance o f some crystalline salts was measured. The electric conductivity of these s alts is influenced by the hydrocarbon radical on the oxygen atom in N-alkox ypyridinium cation more strongly than by the substituent in position 4 of t he pyridine ring.
