Electronic absorption and circular dichroism spectra of Δ-[Os(bipy)2(bipy−)]+, Δ-[Os(bipy)(bipy−)2]0 and Δ-[Os(bipy−)3]−
The electronic absorption and circular dichroism spectra of the complexes produced by the one-, two- and three-electron reduction of Δ-[Os(bipy)3]2+ are reported for the first time. The spectra confirm that, as in the cases of the FeII and RuII analogues, the electrons are localised on the bipyridine ligand and the complexes are correctly formulated [Os(bipy)2(bipy−)]+, [Os(bipy)(bipy−)2]0 and [Os(bipy−)3]−. The absorption spectra of the series of fully reduced complexes [M(bipy−)3]−: M Fe, Ru, Os are compared.
