【摘要】 以水杨醛双缩乙二胺为前驱体,利用简便的液相反应合成了五配位的、具有变形四方锥形结构的Schiff碱双核铜配合物,并通过元素分析、FT-IR、X-射线单晶衍射对其进行结构表征。结果表明,配合物(C16H14Cu N2O2)属于单斜晶系C2/c,a=26.636(5)A,b=6.987 0(14)A,c=14.736(3)A,Z=8,V=2 719.1(9)3,Mr=329.83,F(000)=1 352,R=0.056 0,wR=0.126 3。结构分析表明,该配合物是由两个基本单元C16H14Cu N2O2所组成,每个基本单元由1个Cu(Ⅱ)离子和1个水杨醛双缩乙二胺分子组成。配合物分子之间通过分子间C—H…O氢键的弱相互作用沿晶体学c轴方向组装形成二维网络结构。探究了配合物的荧光和磁性。结果表明,标题配合物相对于自由配体发生了完全的荧光淬灭现象,在10~300 K,配合物具有顺磁性。更多还原

【Abstract】 By taking ethylenediaminesalicylaldehyde as the precursor,a five-coordinated Schiff base binuclear copper complex with distorted square pyramid structures is synthesized in liquid phase reaction and structurally confirmed by elemental analysis,IR and single crystal X-ray diffraction analysis. Complex( C₁₆H)（14）CuN₂O₂) : monoclinic system,space group C2 /c,a = 26. 636（ 5） A,b =6. 987 0（ 14）A,c = 14. 736（ 3） A,Z = 8,V = 2 719. 1（ 9） A3,Mr= 329. 83,F（ 000） = 1 352,R = 0. 056 0,wR = 0. 126 3. The complex is formed by two basic units C₁₆H)（16）CuN₂O₂,each unit consists of a Cu（ Ⅱ） ions and a double-salicylaldehydeethylenediamine molecules. The complex forms two-dimension network with intermolecular C—H…O hydrogen bonds along c axis. The luminescence and magnetic properties of the title cluster are investigated. It has been observed completed fluorescence quenching on the complex in title,comparing to the free ligand,and it is paramagnetic in 10 300 K.更多还原
