Abstract By metathesis between lithium salts of 7, 7, 8, 8-tetracyano-p-quinodimethane and 1-methyl-3-alkylimidazolium bromides, simple radical salts were prepared whose specific electrical conductivity values are c. 10-7-10-3, Ω-1 m-1, according to the donor structure. Combining these salts with neutral 7, 7, 8, 8-tetracyano-p-quinodimethane (TCNQ) gave complex salts with an electrical conductivity higher by 7-3 orders of magnitude which ...
