以对苯二甲酸作为配体,利用水热法合成了含二维(2D)铅无机层的三维(3D)无机-有机杂化材料[Pb2Cl(1,4-BDC)1.5]n(1);利用红外光谱、电感耦合等离子体原子发射光谱、X-射线衍射表征了产物的结构,利用热重分析测定了其热稳定性.结果表明,[Pb2Cl(1,4-BDC)1.5]n属于单斜晶系,P21/c空间群,其晶格参数为:a=0.599 000(10)nm,b=1.185 29(2)nm,c=1.847 37(3)nm,β=91.778 0(10)°,V=1.310 98(4)nm3,Z=4,R1=0.032 0,wR2=0.089 4,Rint=0.043 6.就化合物1的分子结构而言,由Pb—X—Pb(X=O或Cl)链接形成的2D无机层通过对苯二甲酸配体连接,构筑成具有3D骨架的无机-有机杂化材料.
A three-dimensional (3D) inorganic-organic hybrid material [Pb2Cl (1,4-BDC) 1.5] n (1) with a two-dimensional (2D) lead inorganic layer was synthesized by hydrothermal method using terephthalic acid as a ligand. The structure of the product was characterized by infrared spectroscopy, inductively coupled plasma atomic emission spectrometry and X-ray diffraction. The thermal stability of the product was characterized by thermogravimetric analysis. The results showed that [Pb2Cl (1,4-BDC) 1.5] n belongs to In the monoclinic, P21 / c space group, the lattice parameters are a = 0.599 000 (10) nm, b = 1.185 29 (2) nm, c = 1.847 37 ) =, V = 1.31098 (4) nm3, Z = 4, R1 = 0.032 0, wR2 = 0.089 4, Rint = 0.043 6. The molecular structure of compound 1 is represented by Pb-X-Pb Or Cl) are linked by a terephthalic acid ligand to form an inorganic-organic hybrid material having a 3D skeleton.
