利用1,2-双(二苯基膦)乙烷(dppe)与一价铜化合物CuX(X=Cl,Br,ClO4))直接反应得到3个一价铜配合物[CuCl(dppe)]2(μ-dppe).2CH2Cl2(1),[CuBr(dppe)]2(μ-dppe).2DMF(2)和[Cu(dppe)2][ClO4](3),对这些配合物进行结构和光谱表征。结表明,其中二价阳离子部分([{CuX(dppe)}2(μ-dppe)]2+)的结构与已发现的具有与两个铜原子中心连接的一个螯合式和一个桥式的dppe配体的许多其他配合物结构相类似,另外一价阳离子([Cu(dppe)2]+)是一单核铜与2个dppe配体螯合的结构。
Three monovalent copper complexes [CuCl (dppe)] 2 were obtained by direct reaction of 1,2-bis (diphenylphosphino) ethane (dppe) with CuX (X = Cl, Br, ClO4) The structures and structures of these complexes were investigated by the methods of (μ-dppe) .2CH2Cl2 (1), [CuBr (dppe)] 2 (μ-dppe) .2DMF (2) and [Cu (dppe) 2] [ClO4] Spectral characterization. The results indicate that the structure of the divalent cation moiety ([{CuX (dppe)} 2 (μ-dppe)] 2+) is similar to the one found in the chelating and the bridged dppe with two copper atom centers Many other ligands have similar ligand structures, and another monovalent cation ([Cu (dppe) 2] +) is a structure in which mononuclear copper chelates two dppe ligands.
