Abstract

The reaction of lutetium cyclopentadienyl anthracenide complex [(C₅H₅)Lu(C₁₄H₁₀)(THF)₂] with 1 equiv. of 2,2'-bipyridine in THF gives the trinuclear complex [{(η⁵-C₅H₅)Lu}₃(μ₂-Bipy)₃] (I), containing a 2,2'-bipyridine dianion. The complex was isolated as a powder with the composition I·0.1(C₁₄H₁₀)·0.8(C₇H₈). The recrystallization from a toluene/hexane mixture resulted in the crystals of I·0.084(C₁₄H₁₀)·0.831(C₇H₈)·0.500(C₆H₁₄), which were studied by X-ray diffraction (monoclinic group P2₁/c; CCDC no. 2311508). Complex I has an unusual μ₂-κ²N¹,N^1':η⁴N¹,C²,C^2',N^1'-bridging coordination of the dianion.

含 2,2'-联吡啶滇离子的三核镥（III）环戊二烯络合物

摘要环戊二烯基蒽镥络合物[(C5H5)Lu(C14H10)(THF)2]与 1 等量的 2,2'-联吡啶在 THF 中反应，得到含有 2,2'-联吡啶二价的三核络合物[{(η5-C5H5)Lu}3(μ2-Bipy)3](I)。该复合物以粉末形式分离出来，成分为 I-0.1(C14H10)-0.8(C7H8)。从甲苯/己烷混合物中重结晶得到了 I-0.084(C14H10)-0.831(C7H8)-0.500(C6H14)的晶体，并对其进行了 X 射线衍射研究（单斜组 P21/c；CCDC 编号：2311508）。络合物 I 具有不寻常的μ2-κ2N1,N1':η4N1,C2,C2',N1'桥式配位。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
