| 摘要: 采用室温溶液法合成两例新Cu(Ⅱ)配合物[Cu(phen)(H2O)(fba)(ClO4)]·H2O(1),∞1[Cu(bpy)(H2O)(fba)2](2)(Hfba=对甲醛苯甲酸,phen=1,10-邻菲啰啉,bpy=2,2'-联吡啶),通过X-射线单晶衍射、X-射线粉末衍射、红外光谱、热重分析和元素分析方法对其表征。化合物1、2分别为单核、一维链结构,均通过非共价键作用形成三维超分子构造。1和2的变温磁化率研究表明:1中金属离子在300~7和7~2K温度区间分别显示铁磁性和反铁磁性耦合,2中金属离子在测试温度范围内为反铁磁性耦合。 |

| Abstract: Two new Cu(Ⅱ) complexes, [Cu(phen)(H2O)(fba)(ClO4)]·H2O (1) and ∞1[Cu(bpy)(H2O)(fba)2](2)(phen=phenanthroline, bpy=2,2'-bipyridine Hfba=p-formylbenzoic acid) were synthesized by solution-based method and characterized by single-crystal, powder X-ray diffraction methods, IR spectroscopy, TG-DTAanalyses, elemental analyses, and magnetic measurements. Compound 1 is a mononuclear structure crystallizing in the space group P1 and 2 shows a 1D chain structure which belongs to the space group Pbca. Through non-covalent interactions the complex molecules are assembled into 3D supramolecular network structures. The variable temperature magnetic measurements of 1 shows a weak ferromagnetic and antiferromagnetic behavior in the range of 300~7 and 7~2 K, respectively, while the 2's suggests very weak ferromagnetic interactions between Cu(Ⅱ) ions in the experimental temperature range.
