- 論文の詳細を見る
Magnetic circular dichroism (MCD) of <I>cis</I>-dicyanobis(2,2′-bipyridine) iron(II) was measured for a variety of solvents. The visible absorption band is assigned to the lowest "iron(II) to bipyridine" charge-transfer transition. The complex exhibits a significant MCD in its lowest charge-transfer absorption band. The transition shows a shift to higher wave number with an increase in the proton-donating power of solvent. This spectral shift is attributed to hydrogen-bonding interactions of protolytic solvent molecules. In H<SUB>2</SUB>SO<SUB>4</SUB> this dibasic complex is subjected to stepwise protonations. The complex is diamagnetic in protolytic solvents, and even in cone H<SUB>2</SUB>SO<SUB>4</SUB> the diprotonated complex formed is mostly present in the diamagnetic state.
