A New Class of TCNQ Derivatives Easily Generated from TCNQH2Containing Discrete TCNQ2-Anions and Noncoordinating Cations

Readily available, air-stable TCNQH2 affords numerous crystalline derivatives containing discrete TCNQ2− anions, until now a very rare redox level. The work opens the way for the generation of an almost unlimited number of TCNQ-based materials, in a very simple manner, with new structural features and properties.
