【摘要】 为了合成和研究具有磁性和铁电双重性能的配合物,本文选用L-精氨酸(L-Arg)配体与硝酸铜制备了一个配合物,其组成为[Cu(L-Arg)2]2+(NO3-)2·3H2O(1),单晶X射线衍射分析表明,该配合物的晶体结构属于单斜晶系手性空间群C2。磁性和铁电性能测试表明该配合物具有弱的铁磁行为和铁电双重性能。热分析显示该配合物在77-150℃失去自由水,从243℃开始分解。更多还原

【Abstract】 Abstract In order to synthesize and study the complexes with ferromagnetic and ferroelectric behaviors,a copper amino acid complex,namely[Cu(L-Arg)2]2+(NO3-)2·3H2O(1)(L-Arg=L-Arginine)has been prepared from L-Arg and Cu(NO3)2·3H2O.Single-crystal X-ray analysis revealed that complex 1 crystallizes in the monoclinic system with chiral space group C2.Magnetic and ferroelectric studies of complex 1 demonstrated both ferromagnetic and ferroelectric behaviors.Furthermore,the TG analysis of 1 revealed the free water molecules were lost from 77 to 150℃ and it began to chemically decompose after 243℃.更多还原
