ジメチルスルホキシド,N,N-ジメチルホルムアミドおよび炭酸プロピレン中でのハロゲノ鉄(III),鉄(II)錯体の生成

The differences among the Fe (III) and Fe (II) -halide complexes produced in three solvents with different donor numbers, i. e. dimethyl sulfoxide, N, N-dimethylformamide and propylene carbonate were studied. The number of complex species formed in these solvents decreased in the order of propylene carbonate> N, N-dimethylformamide> dimethyl sulfoxide, and the case of formation of higher complexes decreased in the order of >Br^- >I-. The compositions of the complexes which are in equilibrium with Fe" ion in each solvent were determined by the observation of isobestic points.
