Molecular and Crystal Structure Diversity, and Physical Properties of Tetrathiafulvalene Derivatives Substituted with Various Aryl Groups through Sulfur Bridges
intermolecular van der Waals forces and π–π interactions between the aryl groups and between the aryl groups and the TTF core, these TTFs adopt various packing structures. As a typical example, TTF‐14, an achiral molecule, adopts a helicalchain stack through intermolecular atomic close contacts. Moreover, the molecular geometries and packing motifs of these TTFs are sensitive to environmental variation

A series of charge-transfer (CT) complexes have been prepared via diffusion and evaporation methods comprising arylthio-substituted tetrathiafulvalene (Ar-S-TTF) derivatives 1–5 and TCNQF4. Crystallographic studies revealed the diverse crystal packing of the CT complexes, which is related to their flexible structure and the planar central cores of the Ar-S-TTF. The complexes could be divided into three
