Abstract In the course of irradiation of polycrystalline [Cr(en) 3 ] 2 (C 2 O 4 ) 3 · 3 H 2 O at the LF‐excited state wave length substitution of ethylenediamine by the anion presented in the crystal lattice (C 2 O 4 ) 2− occurs and [Cr (en) 2 ox][Cren(ox) 2 ] is formed. Besides products identification spectrophotometric method for the study of the reaction course in the solid state was worked up. Experimental conditions for the utilization of the photosubstitution in solid state in preparative scale were also found.
