Photoredox Decomposition of [Cobalamin-^-NC-Fen(CN)5]3* Induced by Metal-to-Metal Charge Transfer Excitation

چکیده
In the presence of oxygen aqueous solutions of the binuclear complex [cobalamin-^-NCFe(CN)5]3' undergo a redox photolysis (0 ~ 2 x 10'3 at Airr = 405 nm) which yields aquocobalamin and [Fe(CN)6]3\ It is suggested that this photoreaction is induced by direct metal-tometal charge transfer (MMCT) excitation. On the contrary, [cobalamin-fx-NC-Ru(CN)5]3' is photo-inert because a reactive MMCT state is not accessible.

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...

For the mixed-valent chromophore, (NC)5Os-CN-Ru(NH3)5, spin-orbit coupling and ligand-field asymmetry effects lead to multiple visible region intervalence (metal-to-metal) charge transfer transitions (Forlando et al. Inorg. Chim. Acta 1994, 223, 37). The higher energy transition is associated with transfer from an Os 5dπ orbital that is nominally orthogonal to the charge transfer axis. The lowe...
