摘要: 通过双肟配体H₄L(H₄L=6，6′-二羟基-2，2′-[1，2-亚乙基二氧双(氮次甲基)]二酚)与水合乙酸铜反应，合成了一个新的铜配合物{[Cu(HL)(EtOH)]₂Cu}，并进行了元素分析、红外光谱和X-射线单晶衍射测定。结果表明，该配合物为三核结构，由3个Cu^Ⅱ离子、2个配位的(HL)^3-单元、2个配位的乙醇分子组成。且配合物通过分子间C-H…O氢键形成了一个二维超分子结构。

Abstract: A new Cu^Ⅱ complex, {[Cu(HL)(EtOH)]₂Cu} (H₄L=6,6′-dihydroxy-2,2′-[(1,2-ethylenedioxybis(nitrilomethy-lidyne)]diphenol), has been synthesized and characterized by elemental analysis, IR spectroscopy, and X-ray single crystal diffraction method. The results show that the complex consists of three Cu^Ⅱ ions, two pentadentate (HL)^3- units, two coordinated EtOH molecules. The two penta-coordinated Cu^Ⅱ ions of the complex have a slightly distorted tetragonal pyramidal geometry, and the other tetra-coordinated Cu^Ⅱ ion of the complex has a slightly square planar geometry. The crystal packing of the complex shows that a notable feature of this structure resides in the formation of an infinite 2D supramolecular networks through intermolecular C-H…O interactions.
