The crystal chemistry of organic metals. Composition, structure, and stability in the tetrathiafulvalinium-halide systems

Intermolecular energy, structure and stability of regular stacks of tetrathiafulvalene (TTF) and tetracyanoquinodimethane (TCNQ)

“…The latter two structures have stack energies lower by 6.5 to 4.2 kJ mol -~, respectively, than the true eclipsed structure. The importance of electrostatic and metallic interactions in these systems has been pointed out by Scott, La Placa, Torrance, Silverman & Welber (1977). Although our isolated stack atom-atom potential method does not predict the true eclipsed minimum structure, yet it is successful in the prediction of R at constant fi = e = Z = 0.…”

(TTF)Pb2I5: A Radical Cation-Stabilized Hybrid Lead Iodide with Synergistic Optoelectronic Signatures

“…when measured similarly. 43 We believe the increased conductivity can be attributed to the synergistic effect of the inorganic network.…”

Organic Semiconductors and Conductors with tert-Butyl Substituents

“…There is a 4 2 -screw axis parallel to the TTF stack, but is only the two-fold axis along the TCNQ stack. Among charge-transfer salts of TTF derivatives, halides of TTF and o-dimethyl-TTF have tetragonal symmetry [38,39]. In these halides, however, the halogen ions are located on the four-fold axis, and the TTF molecules form regular parallel stacks.…”
