The nacnac Cu(I) compound [LCu(MeCN)] () (L = [{N(CHMe-2,6)C(Me)}CH]) was reacted with complexes containing aromatic -E ([CpFe(η-E)], E = P (), As (), Cp = η-CMe), -P ([Cp‴Co(η-P)] (), Cp‴ = η-CHBu) and -E ligands ([Cp‴Ni(η-E)], E = P (), As ()) yielding the heterometallic complexes [(CpFe)(μ,η-E)(LCu)] (E = P (), As ()), [(CpFe)(μ,η-E)(LCu)] (E = P (), As ()), [(Cp‴Co)(μ,η-P)(LCu)] (), [(Cp‴Co)(μ,η-P)(LCu)] (), and [(Cp‴Ni)(μ,η-E)(LCu)] (E = P (), As ()). These complexes are rare examples of the coordination of a group 11 metal to aromatic -E (E = P, As; = 3-5) ligands. All products were comprehensively characterized by crystallographic and spectroscopic methods. Their dynamic behavior in solution was studied by VT (variable-temperature) NMR spectroscopy, and their electronic structures were elucidated by DFT calculations.
nacnac铜（I）化合物[LCu（MeCN）]（）（L = [{N（CHMe - 2,6）C（Me）}CH]）与含有芳香族-E（[CpFe（η-E）]，E = P（），As（），Cp = η-CMe）、-P（[Cp‴Co（η-P）]（），Cp‴ = η-CHBu）和-E配体（[Cp‴Ni（η-E）]，E = P（），As（））的配合物反应，生成异金属配合物[（CpFe）（μ，η-E）（LCu）]（E = P（），As（））、[（CpFe）（μ，η-E）（LCu）]（E = P（），As（））、[（Cp‴Co）（μ，η-P）（LCu）]（）、[（Cp‴Co）（μ，η-P）（LCu）]（）和[（Cp‴Ni）（μ，η-E）（LCu）]（E = P（），As（））。这些配合物是第11族金属与芳香族-E（E = P，As； = 3 - 5）配体配位的罕见例子。所有产物均通过晶体学和光谱学方法进行了全面表征。通过变温（VT）核磁共振光谱研究了它们在溶液中的动态行为，并通过密度泛函理论（DFT）计算阐明了它们的电子结构。
