ABSTRACT Cyclic bis(diironhexacarbonyl) dithiolates with double-butterfly architecture and centrosymmetricity are supramolecular coordination complexes that mimic the structure and function of the diiron unit in the H-cluster of [FeFe]-hydrogenase. These ferracycles are an important and interesting class of biomimetic iron-carbonyl complexes related to [FeFe]-hydrogenase that have received less attention. This review focuses on the synthetic approaches employed for the formation of the metallo-macrocycles, structural and electronic properties of the macromolecules and influence of bridging ligands, and some aspects of their reactivity.

大环四核双蝶 Fe/S 羰基簇作为 [FeFe]-氢化酶模型

摘要 具有双蝶结构和中心对称性的环状双（二铁六羰基）二硫醇盐是超分子配位复合物，可模拟 [FeFe]-氢化酶 H 簇中二铁单元的结构和功能。这些铁环化合物是一类重要且有趣的与 [FeFe]-氢化酶相关的仿生铁 - 羰基复合物，但很少受到关注。本综述重点关注用于形成金属大环的合成方法、大分子的结构和电子特性以及桥连配体的影响，以及它们反应性的某些方面。图形概要
