Abstract
Unstable novel species produced by photolysis of ferrocene (Cp2Fe) iso lated in low-temperature matrix were studied by means of the Fe-57 Mos sbauer spectroscopy. On the UV-irradiation of Fe-57-enriched ferrocene co-condensed with CCl4 in low-temperature N-2 matrix (20 K), unknown high spin ferrous species (I.S. = 0.90 +/- 0.01 mm/s, Q.S. = 1.94 +/- 0.02 mm/s) were produced as well as ferricinium ion [Cp2Fe](+) (I.S. = 0.52 +/- 0.01 mm/s, Q.S. = 0.0 mm/s). On the annealing, these photopr oducts disappeared to reform ferrocene by the reverse reaction in the matrix. The mechanisms of the photochemical reaction were discussed.
