Abstract
The aqueous ion pair [Co(NH3)(6)](3+)[B12H12](2-) displays an UV absorption at lambda (max) = 250 nm which is assigned to an outer-sphere charge-trans fer (OSCT) transition from [B12H12](2-) to [Co(NH3)(6)](3+). OSCT excitatio n leads to photoredox reaction with the formation of Co2+ (Phi = 0.03 at la mbda (irr) = 313 nm).
