摘　　要：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 new three dimensional （3D） inorganic-organic hybrid framework material containing two dimensional （2D） lead inorganic layer, [Pb2 C1 （1,4-BDC） 1.s ] （1）, was hydro- thermally synthesized in the presence of 1,4-benzenedicarboxylic acid （1,4-HzBDC） as the lig- and. As-synthesized product was characterized by infrared spectrometry, inductively coupled plasma atomic emission spectrometry, and single-crystal X-Ray diffraction, and its thermal stability was evaluated by thermogravimetric analysis. Results indicate that [Pb2 C1 （1, 4- BDC）I.s], belongs to monoclinic system of space group P21/c, with crystal cell parameters of a = 0.599 000 （10） nm, b = 1.185 29（2） nm, c = 1.847 37（3） nm, //= 91.778 0（10）, V = 1.310 98（4） nm3, Z = 4, R1 = 0.032 0, wR2 = 0.089 4, and R,t= 0.043 6. In terms of the molecular structure, compound 1 consists of 3D inorganic-organic hybrid framework composed of 2D inorganic layers of Pb--X--Pb （X = O or C1） networks that are linked by 1,4-BDC groups.
