摘要:

摘要：以5-溴-2-羟基苯基苯甲酮对甲氧基苯甲酰腙为配体与吡啶、氯化铜反应，水热合成制得新型对称双核配合物5-溴-2-羟基苯基苯甲酮对甲氧基苯甲酰腙吡啶铜(Ⅱ) (CCDC:812579)，并培养成单晶。通过元素分析、热重分析和X射线单晶衍射对其结构进行了表征。该配合物晶体属单斜晶系，空间群为P21/c，晶胞参数a=1.62754(17) nm，b=0.83111(9) nm，c=2.35235(17) nm，β= 133.779(4)º，Dc=1.639 mg/m3。配合物的磁性测试结果表明：双核铜配合物分子内存在弱的铁磁性相互作用，而配合物分子间存在弱的反磁性相互作用。

Abstract:Complexes of new symmetrical binuclear 5-bromo-2-hydroxyphenyl benzophenone-methoxy benzoyl hydrazone pyridinecopper(Ⅱ) (CCDC:812579) was synthesized from the reaction of 5-bromo-2-hydroxyphenyl benzophenone-methoxy benzoyl hydrazone with pyridine and copper chloride. And develop into a single crystal. The compound was characterized by elemental analysis, TGA and the crystal structure was determined by X-ray single crystal diffraction. The crystal belongs to the orthorhombic system with space group P21/c, with a=1.62754(17) nm, b=0.83111(9) nm, c=2.35235(17) nm, β=133.779(4)º, Dc=1.639 mg/m3. Complex magnetic results show that: there is a ferromagnetic intramolecular interaction and weak antiferromagnetic intermolecular interaction.
