In this paper, the photochemical properties of ferric complexes are reviewed. The complexes are classified according to the bonding properties of their ligands into classes with unidentate, chelating and macrocyclic ligands. Proteins containing the central atom Fe(III), due to their peculiar properties, are discussed in a separate section. In addition to solution photochemistry, the photoredox processes occurring in microhetcrogeneous systems, polymer matrices and solid complexes are discussed. In each type of complex the main directions for photochemical research are specified and the current knowledge is evaluated. Practical aspects of the photochemistry of ferric complexes are documented.
