The results of an X-ray structure determination of biferrocenium tri-iodide, the dramatic effects of changing from the tri-iodide to the bromoiodide anion upon the temperature of conversion from two Mössbauer doublets to one, and an endothermic differential scanning calorimetry peak at 335 K for biferrocenium tri-iodide indicate that it is lattice dynamics that control the intramolecular electron transfer in mixed-valence biferrocenes.
