摘要:
在水热条件下合成了一个新颖的Pr(Ⅲ)配合物[Pr(pda)0.5(nbca)2(H2O)2](pda=间苯二乙酸,nbca=5-硝基
[1,1'-联苯]3-羧酸),并利用元素分析、X-单晶衍射、红外光谱、热重分析等对其进行表征.结果表明,该配合物属于单斜晶系,空间群为C12/c1,a=2.726 38(13)nm,b=1.010 66(5) nm,c=2.143 87(10)nm,β=94.258(1)°,V=5.891 0(5)nm3,Z=8.晶体结构分析表明:在该配合物中pr3+离子是1个8配位的配合离子,2个配体作为间隔物将稀土金属离子Pr3+链接形成[-Pr-pda-Pr-nbca-]nZ字形链,由5-硝基
[1,1'-联苯]3-羧酸羧基的桥连支撑将1维链拓展为2维(6,6)波浪网面.
Abstract:
A novel two-dimensional(2 D)compound [Pr(1,3-pda)0.5(nbca)2 (H2O)2](pda=1,3-phenylenediacetic acid,nbca=5-nitro
[1,1'-biphenyl]-3-carboxylic acid)was obtained through hydrothermal reaction and characterrized by means of elemental analysis,IR,TG-DSC and single crystal X-ray diffraction.The results show that the compound is monoclinic,with space group C12/c1,a=2.726 38(13)nm,b=1.010 66(5)nm,c=2.143 87(10)nm,β=94.258(1)°,V=5.891 0(5)nm,Z=8.The crystal structure of compound revealed that Pr ion is eight coordination mode in the compound,the pda and nbca ligands bridge the Pr ions to form a [-Pr-pda-Pr-nbca-]n one-dimensional(1D)Z chain.Moreover,these one-dimensional(1D)Z chains are united together through the nbca ligands to afford a 2D(6,6)layer.
