Synthesis and crystal structure of a three dimensional inorganic- organic hybrid framework material containing two dimensional lead inorganic layer based on 1,4- benzenedicarboxylic acid ligand

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.
