摘要
以N,N'-双(3-吡啶)辛二酰胺(L^1)和对苯二乙酸(H_2pda)为混合有机配体,或者以3-(吡啶-3-氨基甲酰)吡嗪羧酸(L^2)为单一有机配体,在水热条件下自组装制备了两种新的铜配合物[Cu(L^1)(pda)(H_2O)_2]·2H_2O(1)和[Cu(L^2)_2](2),并通过红外光谱、元素分析和X-射线单晶衍射对其结构进行了表征。配合物1是由一维[1D[Cu(L^1)]_(2n)^(2n+)链和μ_2-桥连配位模式的pda^(2-)阴离子连接形成的二维层状结构。配合物2是基于单一配体L^2的一种二维层状结构的聚合物。两种配合物的二维层间通过氢键作用拓展成为三维超分子网络。测试了标题配合物修饰的碳糊电极的电化学行为,而且研究了配合物作为催化剂对多种染料分子的光降解活性。
Two new copper compounds, [Cu（ L1 ） （pda） （ H20）2 ] · 2H20（ 1 ） andl Cu（ L2 ）2 ] （2） ,have been hydrothermally pre- pared by selecting the mixedqigands of N, N＇-bis （ 3-pyridyl ） octandiamide （ L1 ） withl, 4-phenylenediacetic acid （ He pda） or the 3- （pyridin-3-ylearbamoyl） pyrazinecarboxylic acid （g2） serving as the single ligand. Two copper compounds have been characterized by the elemental analyses, IR spectra and single crystal X-ray diffraction. Compoundlis a 2D layered structure based on the infinite 1 D [ C u （L1 ） ]2n2n＋ chains and and txe-bridging pda2 anions, while compound2also displays 2D polymeric layer constructed from only the L2 ligand. Furthermore,the adjacent 2D layers for compoundsland2are extended into 3D supramolecule networks by the hydro- gen bonding interactions. The electrochemical behaviors of two title compounds modified carbon paste electrode were studied. Moreo- ver, the photocatalytic degradation abilities for various organic dyes of two compounds have also been investigated.
