Fifty years have passed since the foundation of organometallic neptunium chemistry, and yet only a handful of complexes have been reported, and even fewer have been fully characterized. Yet, increasingly, combined synthetic/spectroscopic/computational studies are demonstrating how covalently bonding, soft, carbocyclic organometallic ligands provide an excellent platform for advancing the fundamental understanding of the differences in orbital contributions and covalency in f-block metal–ligand bonding. Understanding the subtleties is the key to the safe handling and separations of the highly radioactive nuclei. This review describes the complexes that have been synthesized to date and presents a critical assessment of the successes and difficulties in their analysis and the bonding information they have provided. Because of increasing recent efforts to start new Np-capable air-sensitive inorganic chemistry laboratories, the importance of radioactivity, the basics of Np decay and its ramifications (including the radiochemical synthesis of one organometallic compound), and the available anhydrous starting materials are also surveyed. The review also highlights a range of instances in which important differences in the chemical behavior between Np and its closest neighbors, uranium and plutonium, are found.

有机金属N化学

自有机金属n化学技术问世以来已经过去了五十年,但仅报道了少量的配合物,而被充分表征的配合物甚至更少。然而,越来越多的合成/光谱/计算组合研究表明,共价键合的,柔软的碳环有机金属配体如何为推进对f嵌段金属-配体键合中轨道贡献和共价差异的基础理解提供了一个极好的平台。了解微妙之处是安全处理和分离高放射性核的关键。这篇综述描述了迄今为止已合成的复合物,并对它们的分析成功与困难以及所提供的键合信息进行了严格的评估。由于最近为启动新的具有Np功能的空气敏感型无机化学实验室的努力而开展的工作,放射性的重要性,Np衰变的基本原理及其后果(包括一种有机金属化合物的放射化学合成)以及可用的无水起始材料也是调查。审查还重点介绍了一系列实例,其中发现了Np及其最邻近的铀和p之间在化学行为上的重要差异。
