Abstract

The electronic spectra of hydroxo or oxo complexes of the s2 metal ions Tl+, Sn2+, Sb3+, Bi3+ and Te4+ in alkaline solutions display absorption bands in the UV region which are assigned to metal-centered sp transitions. In the case of Tl+ and Sn2+ these sp-excited states are also luminescent. TlOH is photooxidized to Tl2O3 by molecular oxygen while the photooxidation of Sn(OH)3 - to Sn(OH)6 2- is even achieved by water which is reduced to hydrogen. Both complexes produce hydrated electrons upon 266 nm laser excitation. No electron ejection can be observed for the hydroxo or oxo metalates of Sb3+, B3+ and Te4+, which undergo a photoreduction to the metallic state with a concomitant oxidation of hydroxide to hydrogen peroxide and/or oxygen.
