Studies in the field of organic metals 3. Nonstoichiometric tetraselenotetracene iodides
- 17 Downloads
A study has been made of the reactions of tetraselenotetracene with iodine, and measurements have been made on single crystals of the four nonstoichiometric complexes resulting from these reactions.
It is characteristic that the crystals of these complexes are built up around two independent sublattices, the one for the tetraselenotetracene and the other for the iodine.
A study of the ESR, electronic, and IR spectra showed that the tetraselenotetracene complexes with iodine are mixed-valence compounds.
Measurements on individual crystals showed that the conductances of the complexes remained essentially constant over certain well-defined temperature intervals.
