摘要

从基础的角度来看，对含有二茂铁单元的新型杂价配合物进行研究的动机在于改进和扩展电子转移模型和理论的前景。在此，我们将二茂铁基催化剂 Fc3E 系列扩展到了更重的类似物（E = As、Sb 和 Bi），并以 Fc3P 为参照研究了桥接原子的影响。电化学研究阐明了静电作用对化合物表现出的大氧化还原分裂（ΔE1）以及 Fc3As 溶剂稳定性的影响。结合光谱电化学研究对三铁氧体二茂镍的结构特性进行的分析表明，相关阳离子[Fc3E]+中存在微弱的电子耦合，这表明存在一种通空机制。

Electronic Coupling in Triferrocenylpnictogens

From a fundamental perspective, studies of novel mixed-valent complexes containing ferrocenyl units are motivated by the prospect of improving and extending electron transfer models and theories. Here, the series of triferrocenylpnictogens Fc₃E was extended to the heavier analogues (E = As, Sb, and Bi), and the influence of the bridging atom was investigated with Fc₃P as a reference. Electrochemical studies elucidate the effect of electrostatic contribution on the large redox splitting (ΔE₁) exhibited by the compounds and solvent stabilization in the case of Fc₃As. Structural characterization of the triferrocenylpnictogens combined with spectroelectrochemical studies indicates weak electronic couplings in the related cations [Fc₃E]⁺, suggesting a through-space mechanism.
