The blue 19e complex [FeIII(C5Me5)(η2-S2CNMe2)2]1, generated by addition of NaS2CNMe2 to the 17e complex [FeIII(C5Me5)(η2-S2CNMe2)(MeCN)]PF6 in MeCN at â45 °C or by monoelectronic reduction of the 18e cation 1+ using the 19e complex [FeI(C5H5)(C6Me6)] in THF at â80 °C gives the purple 17e form [FeIII(C5Me5)(η2-S2CNMe2)-η1-SC(S)NMe2}]2 in solution and in the solid state; both the 17e and 19e forms are characterized by their specific ESR and Mössbauer spectra and by cyclic voltammetry.
蓝色 19e 复合物[FeIII(C5Me5)(δ-2-S2CNMe2)2]1、在 MeCN 中将 NaS2CNMe2 加入 17e 复合物 [FeIII(C5Me5)(δ-2-S2CNMe2)(MeCN)]PF6,或者在â45 °C下,在THF中使用19e配合物[FeI(
C5H5)(C6Me6)]对18e阳离子1+进行单电子还原,在â80 °C下生成紫色的17e形式[FeIII(C5Me5)(δ-2-S2CNMe2)-δ-1-SC(S)NMe2}]2;17e 和 19e 两种形式均可通过其特定的 ESR 和 MÃssbauer 光谱以及循环伏安法进行表征。
