report a family of hybrid [2]rotaxanes based on inorganic [Cr7NiF8(O2CtBu)16]− (“Cr7Ni}”) rings templated about organic threads that are terminated at one end with pyridyl groups. These rotaxanes can be coordinated to [Cu(hfac)2] (where Hhfac = 1,1,1,5,5,5-hexafluoroacetylacetone), to give 1:1 or 1:2 Cu:Cr7Ni} adducts: [Cu(hfac)2](py-CH2NH2CH2CH2Ph)[Cr7NiF8(O2CtBu)16]}, [Cu(hfac)2][py-CH2NH2CH2CH
我们报告了一系列基于无机 [Cr7NiF8(O2CtBu)16]- (“Cr7Ni}”) 环的杂化 [2] 轮烷家族,这些环以有机线为模板,末端为吡啶基。这些轮烷可以与 [Cu(hfac)2](其中 Hhfac = 1,1,1,5,5,5-六氟乙酰丙酮)配位,得到 1:1 或 1:2 Cu:Cr7Ni} 加合物:[ Cu(hfac)2](py-CH2NH2CH2CH2Ph)[Cr7NiF8(O2CtBu)16]},[Cu(hfac)2][py-CH2NH2CH2CH3][Cr7NiF8(O2CtBu)16]},[Cu(hfac)2] ([py-CH2CH2NH2CH2C6H4SCH3][Cr7NiF8(O2CtBu)16])2},[Cu(hfac)2]([py-C6H4-CH2NH2(CH2)4Ph][Cr7NiF8(O2CtBu)16])2},和 [Cu(hfac)2]([
