Abstract

In this mini-review of our research group's activity, the application of Fe Mössbauer spectroscopy in studies of electronic structure, coordination environment, and magnetic interactions in an interesting series of Fe(II/III) compounds selected is discussed. We selected two prominent phenomena that arose during investigations of selected groups of compounds carried out at different periods of time: (1) very high magnetic hyperfine fields observed at low temperatures; (2) changes in the oxidation state of the central iron atom of complexes in the solid state during interactions with gaseous O/HO mixtures, resulting in spin crossover (SCO).

摘要

在本研究小组活动的简要回顾中，讨论了 Fe Mössbauer 光谱学在一系列有趣的 Fe(II/III)化合物的电子结构、配位环境和磁相互作用研究中的应用。我们选择了在不同时期对选定化合物组进行研究时出现的两个突出现象：(1) 在低温下观察到的非常高的磁超精细场；(2) 在与气态 O/HO 混合物相互作用时，配合物中心铁原子的氧化态在固态中发生变化，导致自旋交叉 (SCO)。
