摘要

在溴化铜（II）存在下，2-（1H-吡咯-1-基）乙醇与 3-羟基黄酮反应生成二聚铜（II）络合物 [μ-O-（κ2-O,O-flav）（κ2-N,O-2PEO）Cu]2 (1)（flav = 3-羟基黄酮酸，2PEO = 2-（1H-吡咯-1-基）乙酸酯）；2PEO = 2-(1H-吡咯-1-基)乙醇酸酯），其中 flav 和 2PEO 配体均以κ2 键模式与铜（II）原子结合。二聚体通过桥接在两个铜原子之间的氧原子进行静电保持。通过单晶 X 射线衍射、红外光谱、紫外可见光谱、元素分析和熔点测定，对复合物 1 进行了表征。该复合物在单斜空间群 P21/n (14) 中结晶，晶胞值为 a = 11.85340(10) Å，b = 8.51480(10) Å，c = 23.8453(2) Å；β = 99.3920(10)°。

A (2-(Pyrrolidin-1-yl)ethan-1-olate)(1-oxo-3-phenyl-1,4-dihydronaphthalen-2-olate) μ-Oxo-Bridged Dicopper(II) Dimeric Complex

The reaction of 2-(1H-pyrrol-1-yl)ethanol with 3-hydroxyflavone in the presence of copper(II) bromide yielded a dimeric copper(II) complex, [μ-O-(κ2-O,O-flav)(κ2-N,O-2PEO)Cu]2 (1) (flav = 3-hydroxyflavonolate; 2PEO = 2-(1H-pyrrol-1-yl)ethanolate) with both the flav and 2PEO ligands bound to the copper(II) atom in a κ2-bonding mode. The dimer is held electrostatically by bridging oxygen atoms between two copper atoms. Complex 1 was characterized by single-crystal X-ray diffraction, infrared, and UV-Vis spectroscopy, elemental analysis, and melting point determination. The complex crystallizes in the monoclinic space group P21/n (14) with cell values of a = 11.85340(10) Å, b = 8.51480(10) Å, c = 23.8453(2) Å; β = 99.3920(10)°.
