摘要
开壳碳烯的特点是碳烯碳中心有两个未成对电子，是一种极不稳定的化合物，通常以激发态形式出现。现在，两种三重金属碳烯已通过过渡金属和硅基取代基得到稳定；这些化合物已通过单晶 X 射线衍射、光谱和量子化学分析等多种技术进行了表征。
Open-shell carbenes, which feature two unpaired electrons on a carbene carbon centre, are highly unstable compounds and are usually observed as excited-state species. Now, two triplet metallocarbenes have been stabilized by transition-metal and silyl substituents; the compounds have been characterized by various techniques including single-crystal X-ray diffraction, spectroscopy and quantum-chemical analyses.
期刊介绍：
Nature Chemistry is a monthly journal that publishes groundbreaking and significant research in all areas of chemistry. It covers traditional subjects such as analytical, inorganic, organic, and physical chemistry, as well as a wide range of other topics including catalysis, computational and theoretical chemistry, and environmental chemistry.
The journal also features interdisciplinary research at the interface of chemistry with biology, materials science, nanotechnology, and physics. Manuscripts detailing such multidisciplinary work are encouraged, as long as the central theme pertains to chemistry.
Aside from primary research, Nature Chemistry publishes review articles, news and views, research highlights from other journals, commentaries, book reviews, correspondence, and analysis of the broader chemical landscape. It also addresses crucial issues related to education, funding, policy, intellectual property, and the societal impact of chemistry.
Nature Chemistry is dedicated to ensuring the highest standards of original research through a fair and rigorous review process. It offers authors maximum visibility for their papers, access to a broad readership, exceptional copy editing and production standards, rapid publication, and independence from academic societies and other vested interests.
Overall, Nature Chemistry aims to be the authoritative voice of the global chemical community.
