Abstract
Abstract Compounds having a cation which is tetrathiafulvalene of 2,5-cyclohexadiene-1,4-diylidene-bis-1,3-dithiole or both, and an anion which is 7,7,8,8-tetracyano-p-quinodimethane or 11,11,12,12-tetracyano-2,6-naphthaquinonedimethane or both, are described. The above compounds are characterized by anions and cations which are both odd-electron species.
