A complex radical ionic salt, N-(beta-iodoethyl)pyridinium bis(7,7',8,
8'-tetracyanoquinodimethanide), (C7H9IN)(+).(TCNQ)(.-).(TCNQ), where T
CNQ is 7,7',8,8'-tetracyanoquinodimethane, was synthesized and studied
by X-ray structural analysis. The crystal structure of the complex co
nsists of layers. Layers of (C7H9IN)(+) cations alternate with layers
of TCNQ molecules packed in stacks. Shortened intermolecular contacts
occur in stacks of TCNQ and between cationic and anionic layers.
