正确的能级次序应与分子的活性位置一致.实验证实,铁硫蛋白或模型化合物Fe_2S_2(SR)~(2-)及Fe_4S_4(SR)_4~(2-)的活性位置在端基,易于发生多种取代反应,而Fe_2S_2和Fe_4S_4实一般是稳定的.但是,经过电化学还原生成的Fe_2S_2(SR)_4~(3-),却不可逆地二聚化,生成Fe_4S_4(SR)_4~(2-)
The correct order of the energy levels should be consistent with the active site of the molecule, and the activity of the iron-sulfur protein or the model compounds Fe2S2 (SR) 2- and Fe4S4- (2-4) However, Fe_2S_2 (SR) _4 ~ (3-) formed by electrochemical reduction irreversibly dimerizes to Fe_4S_4 (SR) _4 ~ (3) 2-)
