The temperature transformation of the hyperfine structure of the EPR spectra of mixed-valence molecular crystals is considered. A strong intercluster interaction stabilizing the charge-ordered phase is taken into account. In this model, the "localization-delocalization" type of spectrum transformation arises from the "spatial", but not from the "dynamical" electron-density redistribution. Concrete evaluations for Cu(I)-Cu(II) cluster are given.
