Electron transfer in macromolecule-metal complexes.

Electron transfer between metal complexes: retrospective.

Electron transfer and catalysis with high-valent metal-oxo complexes.

High-valent metal-oxo complexes are produced by reductive activation of dioxygen via reduction of metal complexes with reductants and dioxygen. Photoinduced electron transfer from substrates to metal complexes with dioxygen also leads to the generation of high-valent metal-oxo complexes that can oxygenate substrates. In such a case metal complexes act as a photocatalyst to oxygenate substrates ...

Light Induced Electron Transfer Reactions of Metal Complexes

Properties of the excited states of tris(2,2'—bipyridine) and tris(l,lO—phenanthroline) complexes of chromium(III), iron(II), ruthenium(II), osmium(II), rhodium(III), and iridium(III) are described. The electron transfer reactions of the ground and excited states are discussed and interpreted in terms of the driving force for the reaction and the distortions of the excited states relative to th...

Photochemistry and electron-transfer mechanism of transition metal oxalato complexes excited in the charge transfer band.

The photoredox reaction of trisoxalato cobaltate (III) has been studied by means of ultrafast extended x-ray absorption fine structure and optical transient spectroscopy after excitation in the charge-transfer band with 267-nm femtosecond pulses. The Co-O transient bond length changes and the optical spectra and kinetics have been measured and compared with those of ferrioxalate. Data presented...

METAL-METAL CHARGE TRANSFER IN LnM-CN-FeCl3 COMPLEXES

By combining the organometallic cyanides L n M-CN [L n M = Cp(dppe)Fe, Cp(dppe)Ru, Cp(PPh 3 ) 2 Ru] with FeCl 3 the dinuclear complexes L n M-CN-FeCl 3 were obtained. Structure determinations have revealed configurations close to linear arrays Fe-C-N-Fe and Ru-CN-Fe. From the n(CN) band positions in their IR spectra it can be concluded that FeCl 3 is a very strong electron acceptor. Accordingly...
