S.B. Erenburg,* N.V. Bausk, L.G. Lavrenova, L.N.Mazalov find application as materials for optical memory where information can be recorded, for example, with the help of local heating by several degrees (above 300 K) with a thin laser beam and stored at room temperature. Such a two-dimensional picture can be read and then erased by cooling. Since no one has, so far, succeeded in obtaining well crystallized polymeric compounds of this type, EXAFS (Extended X-ray Absorption Fine Structure) spectroscopy gives almost the only possibility to characterize their structural parameters. The goal of the present work is to realize this possibility, try to reveal light-induced spin crossover of Fe (II) polymeric complexes and to perform direct structural study of light-induced HS states of solid Fe (II) complexes at the first time.
