采用水热方法合成一种新型的稀土有机配合物[Pr(2,5-pdc)(OH)(H2O)2].H2O,通过元素分析、红外光谱及X射线衍射方法对该配合物进行结构表征.结构分析表明:标题配合物属于单斜晶系;P21/c空间群;晶胞参数a=0.9350(4)nm,b=1.6158(6)nm,c=0.8309(3)nm,α=γ=90.000°,β=94.078(7)°,V=1.2521(9)nm3,Z=4.配合物中镨离子通过μ2-OH桥连接形成双核构筑单元,进一步通过2,5-pdc中的羧基氧原子连接形成三维结构.
A novel rare earth organic complex [Pr (2,5-pdc) (OH) (H2O) 2] .H2O was synthesized by hydrothermal method. The structure of the complex was characterized by elemental analysis, IR and X-ray diffraction Characterization. The structural analysis showed that the title complex belongs to the monoclinic system; P21 / c space group; a = 0.9350 (4) nm, b = 1.6158 γ = 90.000 °, β = 94.078 (7) °, V = 1.2521 (9) nm3, Z = 4. The praseodymium ions in the complex are connected by μ2-OH bridge to form the binuclear building block, The carboxyl oxygen atoms are linked to form a three-dimensional structure.
