采用乙二胺水杨醛Schiff碱配体与水合硝酸铜配位生成了一雁形的双核Cu(Ⅱ)配合物,产物通过了元素分析、红外光谱及单晶X射线衍射分析等手段的证实。结果表明,该配合物晶体属于单斜晶系,P21/c空间群,晶胞参数为:a=0.8559(14),b=2.3276(4),c=1.1057(18)nm,β=91.360(4)°,V=2.2021(6)nm3,Z=2,Dc=1.706g/cm3,Mr=1130.82,R1=0.0543,wR2=0.1522;结构分析表明,配合物中存在两种截然不同的Cu(Ⅱ)配位模式,Cu(1)离子采取四方平面构型,Cu(2)离子却为扭曲八面体几何构型。
The use of ethylenediamine salicylaldehyde Schiff base ligand and copper nitrate hydrate to form a goose-shaped binuclear Cu (Ⅱ) complex, the product by elemental analysis, infrared spectroscopy and single crystal X-ray diffraction analysis and other means to confirm . The results show that the crystal belongs to the monoclinic space group P21 / c with unit cell parameters of a = 0.8559 (14), b = 2.3276 (4), c = 1.1057 (18) nm and β = 91.360 4) °, V = 2.2021 (6) nm3, Z = 2, Dc = 1.706g / cm3, Mr = 1130.82, R1 = 0.0543 and wR2 = 0.1522. Structural analysis showed that there are two distinct Cu Ⅱ) coordination mode, Cu (1) ions adopt a tetragonal plane configuration, but Cu (2) ions are distorted octahedral geometry.
