ligand to provide supramolecular design using halogen⋅⋅⋅halogen interactions within an FeIII system that has the potential to undergo spin crossover (SCO). By removing the solvent from the crystal lattice, we “switch on” halogen⋅⋅⋅halogen interactions between neighboring molecules, providing a supramolecular cooperative pathway for SCO. Furthermore, changes to the halogen‐based interaction allow us to modify
我们将 Re IV X 5 } − (X=Br, Cl) 合成子添加到基于口袋的配体中,以使用 Fe III系统内的卤素·····卤素相互作用提供超分子设计,该系统有可能发生自旋交叉(上合组织)。通过从晶格中去除溶剂,我们“打开”相邻分子之间的卤素·····卤素相互作用,为 SCO 提供了超分子合作途径。此外,卤素相互作用的改变使我们能够改变 SCO 事件的温度和性质。
