合成了一系列具有cis-HN = NH配体的硫醇桥联二铁簇合物[Cp+Fe（mu-SEt）（2）-（mu-eta（1）：eta（1）-HN = NH）FeCp+][PF 6]（Cp+ = eta（5）-C5 Me 4 H或eta（5）-C5 Me 5），并通过光谱学和X射线晶体学进行了表征.在温和的条件下，这些新的Fe/S簇合物表现出很高的活性，不仅对肼的N-N键的催化断裂，而且对末端炔的活化和偶联也有很高的活性。
A series of well-defined thiolate-bridged diiron clusters bearing the cis-HN = NH ligand, [Cp+Fe(mu-SEt)(2)-(mu-eta(1):eta(1)-HN = NH)FeCp+][PF6] (Cp+ = eta(5)-C5Me4H or eta(5)-C5Me5), are successfully prepared in high yields and fully characterized by spectroscopy and X-ray crystallography. Under moderate conditions, these new Fe/S clusters exhibit high activity, not only for the catalytic cleavage of the N-N bond of hydrazines but also for the activation and coupling of terminal alkynes.
