摘要
通过Salen型双肟配体H2L1(H2L1=5,5′-二(N,N′-二乙胺)-2,2′-[乙二氧双(氮次甲基)]二酚)与乙酸铜反应,合成了一种双核铜(Ⅱ)配合物[Cu2(L2)2](H2L2=4-(N,N′-二乙胺)水杨醛O-(2-羟乙基)肟),并对其进行了X-射线衍射单晶结构分析。在形成配合物时,铜!离子的催化作用导致Salen型双肟配体的1个N-O键发生了断裂,意外地得到了一种新颖的含有Cu-O-Cu-O四元环中心的烷氧基氧桥联的双核铜(Ⅱ)配合物,而不是预期的Salen型双肟Cu-N2O2配合物。
A unprecedented dinuclear copper(R) complex, [Cu2(L2)2] (H2L2=4-(N,N'-diethylamino)salicylaldehyde O- (2-hydroxyethyl)oxime), has been synthesized through the complexation of copper(1) acetate monohydrate with ligand H2L1 (H2L1=5,5'-di(N,N'-diethylamino)-2,2'-[ethylenedioxybis(nitrilomethylidyne)]diphenol). The crystal structure of the copper(1) complex has been determined by single crystal X-ray diffraction method. The catalysis of copper(1) ions results in the unexpected cleavage of one of the N-O bonds in the ligand H2L1, giving a novel dialkoxo-bridged dinuclear complex possessing a Cu-O-Cu-O four-membered ring core instead of the usually desired Salen-type bisoxime Cu-N2O2 complex.
