本文综述了多卤素化学的发展领域，特别是多卤素阴离子(多卤化物)。除了历史概要外，还说明了导致多氟化物、多氯化合物、多溴化合物和多卤化物形成的合成方法的当前进展。在过去的十年里，多卤化物的结构多样性大大增加，特别是多氯化物和多溴化物，它们通常通过单晶X射线衍射、拉曼光谱和量子化学计算来表征。通过最先进的量子化学计算对多氟化合物进行了检验，并在4K低温条件下的稀有气体基质隔离实验中进行了光谱研究。此外，还讨论了此类多卤化物体系中的成键。最后一节介绍了此类多卤化物在卤化反应、电化学以及作为活性离子液体方面的应用，强调了多卤素化学领域的前景。
This review deals with the evolving field of polyhalogen chemistry, specifically polyhalogen anions (polyhalides). In addition to a historical outline, current progress in synthetic approaches leading to the formation of polyfluorides, polychlorides, polybromides, and polyinterhalides are also illustrated. The structural diversity of polyhalides has dramatically increased in the past decade, especially for polychlorides and polybromides, which are commonly characterized by single-crystal X-ray diffraction, Raman spectroscopy, and quantum-chemical calculations. Polyfluorides were examined by sophisticated state-of-the-art quantum-chemical calculations and investigated spectroscopically in rare gas matrix-isolation experiments under cryogenic conditions at 4 K. In addition, the bonding in such polyhalide systems is discussed. The last section deals with applications of such polyhalides in halogenation reactions, electrochemistry as well as their use as reactive ionic liquids, emphasizing the promising future of the field of polyhalogen chemistry.
