Charge ordering and phase transitions in mixed-valence biferrocenium derivatives crystals are considered using a new approach (referred to as quasidynamical model) to the cooperative vibronic problem. The explanation of the complex Mössbauer spectra involving both localized and delocalized components is given with particular attention to the quantum effects of vibronic resonances.
