| 摘要: 2种新的水杨醛型单肟配体HL1(HL1=(E)-2-{1-甲氧基亚氨基甲基}-4，6-二溴苯酚)和HL2(HL2=(E)-2-{1-乙氧基亚氨基甲基}-4-硝基苯酚)分别与一水合乙酸铜反应，合成了2个铜配合物[Cu(L1)2](1)和[Cu(L2)2](2)，利用元素分析、红外光谱和紫外光谱等进行了表征，并用X-射线单晶衍射测定了其晶体结构。结果表明，配合物1、2均为单核结构，由1个CuⅡ离子和2个配体组成。中心CuⅡ离子的配位数是4。配合物1为扭曲的平面四边形，而2为规则的平面四边形。配合物1以分子间氢键形成了无限的一维链状超分子结构，而配合物2以分子间氢键和π…π作用形成了二维超分子结构。 |

| Abstract: Two new CuⅡ complexes, [Cu(L1)2] (1) (HL1=(E)-3,5-dibromo-2-hydroxybenzaldehyde O-methyl oxime) and [Cu(L2)2] (2) (HL2=(E)-2-hydroxy-5-nitrobenzaldehyde O-ethyl oxime), have been synthesized and characterized by elemental analyses, IR spectra, UV-Vis spectra and X-ray diffraction methods. X-ray crystallographic analyses show that complexes 1 and 2 are mono-nuclear structure. The four-coordinated CuⅡ atoms of the two complexes lie in the N2O2 coordination sphere of two mono-oxime ligands, and complex 1 has a square planar geometry distorted tetrahedrally, whereas complex 2 has a regular square planar geometry. Complex 1 forms an infinite 1D chain-like supramolecular structure by intermolecular hydrogen bonds, while complex 2 forms an infinite 2D supramolecular structure by intermolecular hydrogen bonds and π…π packing interaction.
