Abstract It has been shown that the photochemical properties of the M(CN)/sub 6//sup 2 -/ (M = Co(III), Rh(III), Ir(III)) complexes are parallel, each giving the pentacyanoaquo complex as the only photoproduct when photolysis is conducted in acidic aqueous media. However, of these only Co(CN)/sub 6//sup 3 -/, which displays a wave-length-independent quantum yield for photoaquation of 0.31 +/- 0.02 mol/einstein, has had its solution photosubstitution properties quantitatively characterized. Reported here are quantitative investigations of the photosubstitutions displayed by the Rh(CN)/sub 6//sup 3 -/ and Ir(CN)/sub 6//sup 3 -/ ions in acidic aqueous solution at 25/sup 0/C. Also reported are the low-temperature (77K) luminescence spectra and emission lifetimes of these species and of the photoproducts M(CN)/sub 5/H/sub 2/O/sup 2 -/. 39 references, 4 figures, 3 tables.
