摘　　要：在溶剂热条件下,合成了2个铜的双核配合物[Cu(tpyc)(H_(2)btc)]_(2)(1)、[Cu_(2)(tpyc)_(2)(suc)(H_(2)O)_(2)](2)和配位聚合物{[Cu_(3)(tpyc)_(3)(OH)_(2)(H_(2)O)_(2)]Cl O_(4)}_(n)(3)(H_(3)btc=1,3,5-benzenetricarboxylic acid,H_(2)suc=succinic acid,Htpyc=2,2’∶6’2″-terpyridine-4’-carboxylic acid),分别用元素分析、红外光谱、X射线单晶衍射、粉末X射线衍射、热重及磁性分析对其进行了表征。结构分析表明,配合物1~3通过多重氢键作用形成三维超分子结构。磁性分析表明:配合物1的相邻Cu.离子间存在铁磁耦合作用,配合物2的相邻Cu(Ⅱ)离子间存在反铁磁相互作用。Two copper binuclear complexes[Cu(tpyc)(H_(2) btc)]_(2)(1),[Cu_(2)(tpyc)_(2)(suc)(H_(2) O)_(2)](2)and one coordination polymer{[Cu_(3)(tpyc)_(3)(OH)_(2)(H_(2) O)_(2)]ClO_(4)}_(n)(3)(H_(3) btc=1,3,5-benzenetricarboxylic acid,H_(2) suc=succinic acid,Htpyc=2,2’∶6’2″-terpyridine-4’-carboxylic acid)have been synthesized under solvothermal conditions and characterized by elemental analysis,FT-IR spectroscopy,single-crystal X-ray diffraction,powder X-ray diffraction,thermogravimetric analysis and magnetic analysis.Structural analysis suggests that complexes1-3 display 3 D supramolecular networks by multiple hydrogen-bonding interactions.Magnetic studies show that ferromagnetic coupling exists between Cu.ions in complex1,while antiferromagnetic interaction exists between Cu(Ⅱ)ions in complex2.CCDC:1950190,1;1950191,2;1950202,3.
