Abstract

X-ray single crystal diffraction demonstrates that in {[Pb ₂(HNTP)₂(NTP)(CHZ)(H₂O)₂]·2. 5H₂O} _n (polymer, NTP = nitroterephthalate, CHZ = carbohydrazide), there are two kinds of Pb centers. By means of the bridging ligands-two water, two CHZ and two NTP molecules, four Pb centers (two Pb1 and two Pb2) are joined together to form the rectangular grid, and by the intense static electric interactions among the two O atoms of nitro groups in NTP, the extending two-dimensional grids are linked together to form the three-dimensional frameworks. Thermal analyses DSC and TG-DTG have been performed on the polymer to study its thermal decomposition mechanism and thermal kinetic properties.
