Abstract
The aqueous ion pair [Co(NH3)6]3+[B12H12]2- displays an UV absorption at λmax = 250 nm which is assigned to an outer-sphere charge-transfer (OSCT) transition from [B12H12]2- to [Co(NH3)6]3+. OSCT excitation leads to photoredox reaction with the formation of Co2+ (Φ = 0.03 at λirr = 313 nm).
