CH3ReO3 undergoes a charge-transfer interaction with Fe(CN)(6)(4-) in
aqueous solution. It is assumed that the labile binuclear complex [(Me
)O3Re(mu-NC)Fe(CN)(5)](4-) is formed. It is characterized by a metal-t
o-metal charge transfer absorption at lambda(max) = 437 nm. Upon Fe(II
) to Re(VII) charge transfer excitation, a redox photolysis takes plac
e yielding [Fe(CN)(6)](3-) as oxidation product with phi = 0.033 at la
mbda(irr) = 436 nm.
