摘要 采用溶液法在室温水·乙醇溶液中,以CuCl2·2H2O、一水合邻菲哕啉(Phen·H2O)和对氰基苯甲酸(P-CNC6H4COOH,HCBA)为原料合成了标题配合物[Cu(Phen)(H2O)(CBA)C1]·H2O通过X-射线衍射法测定配合物的晶体结构,结构分析表明,中心Cu(II)离子配位数为5,构成CuN2O2C1四方锥配位模式。通过O—H…O氢键形成一维超分子带,超分子带又经带间C—H…0氢键作用形成超分子层,并经C—H…N氢键作用堆积组装形成三维超分子构造。并对其进行红外光谱、元素分析、粉末x一射线衍射、差热分析等表征。对配合物磁性做了进一步测试,在2—300K区间遵循韦斯定理Xm(T+0.10):0.44cm3·K·mol^-1。并采用VanVleck方程对配合物进行了拟合,最佳拟合结果为g=2.156(1),zJ’=-0.138(4),一致性因子为R=3.607×10^-8。磁性测试结果表明Cu(II)离子之间存在较弱的反铁磁耦合作用。 Reaction of CuC12 · 2H2 O, 1,10-phenanthrolineand p-cyan-benzoic acid in aqueous ethanol solutions formed the title complex [ Cu (Pben) ( H2O ) ( CBA ) C1 ]·H2O ( Phen = 1, 10-phenanthroline, HCBA = p-cyan-benzoic acid). X-ray analysis reveals the Cu( II ) ion of the title compound is five-co- ordinated,forming a square pyramidal CuN2O2Cl coordination environment. The compex extended into one-dimensional supramolecular belts via O--H… 0 hydrogen bonds, which are linked by C--H … 0 hydrogen bonds into two-dimensional layers. The layers are finally extended into three-dimensional supramolecular network by C--H... N hydrogen bonds. And the compound was further characterized by IR spectroscopy, TG/DTA analyses, elemental analyses, powder X-ray diffraction, and magnetic measurements. The temperature dependence of the magnetic susceptibility of the compound follows a Curie-weiss law m = C/( T - O) , and the Xm can be fit to the Van Vleck equation with the best fit results in g = 2. 156( 1 ) , zJ' = - 0. 138 (4) , and R = 3. 607 × 10^-8, suggesting a weak antiferromagnetic coupling among Cu(II) ions.
