Key challenges in modern synthetic chemistry include the design of reliable, selective, and more sustainable synthetic methods, as well as the development of promising candidates for new materials. Molecular bismuth compounds offer valuable opportunities as they show an intriguing spectrum of properties that is yet to be fully exploited: a soft character, a rich coordination chemistry, the availability of a broad variety of oxidation states (at least +V to -I) and formal charges (at least +3 to -3) at the Bi atoms, and reversible switching between multiple oxidation states. All this is paired with the status of a non-precious (semi-)metal of good availability and a tendency towards low toxicity. Recent findings show that some of these properties only come into reach, or can be substantially optimized, when charged compounds are specifically addressed. In this review, essential contributions to the synthesis, analyses, and utilization of ionic bismuth compounds are highlighted.
现代合成化学面临的主要挑战包括设计可靠、选择性和更可持续的合成方法，以及开发有前途的新材料候选物。分子铋化合物提供了有价值的机会，因为它们表现出一系列有趣的尚未得到充分利用的性质：软性质、丰富的配位化学、多种氧化态（至少为 +V 至 -I）和价态（至少为 +3 至 -3）在 Bi 原子上，以及多个氧化态之间的可逆转换。所有这些都与一种非贵金属（半）金属的良好可用性和低毒性倾向相结合。最近的研究结果表明，当专门研究带电化合物时，其中一些性质才开始显现，或者可以得到实质性的优化。在这篇综述中，突出了对离子铋化合物的合成、分析和利用的重要贡献。
