A wide range of heterocyclic sulfur-nitrogen and selenium-nitrogen radicals have been characterized in recent years. Synthetic routes to these materials are summarized, and the modes of association which they exhibit in the solid state are illustrated. The potential use of these radicals as building blocks for low-dimensional molecular conductors is outlined, and some strategies for generating specific solid state architectures are explored. Recent attempts to prepare conductive materials from custom-built bifunctional 1, 2, 3, 5-dithia- and diselenadiazolyls are described.read more

TL;DR: Variable-temperature magnetic susceptibility measurements indicate that antiferromagnetic exchange between radicals along the pi-stacks increases with pi-stack slippage, and the origin of the dramatically different magnetic behavior across the series has been explored in terms of a direct through-space mechanism by means of DFT calculations on individual pairwise exchange energies.

Crystal Structure of TTF·BTDA–TCNQ Complex. A New Type of CT Complex with an Inclusion Behavior and a Multi-Dimensional Structure
TL;DR: The crystal structure of TTF·BTDA-TCNQ complex was determined by an X-ray diffraction method as discussed by the authors, which is not a simple CT complex with mixed stacks but rather the one with some inclusion behavior.
