A novel one-dimensional metal-organic coordination polymer, [Zn (NH3)2(BDC)]n (BDC=1,4-benzenedicaboxylate), has been synthesized by solvent evaporation method through self-assembly of Zn (II) salts with terephthalic acid ligand in ammonia aqueous solution. Single crystal X-ray diffraction analysis indicated that each Zn (II) was coordinated by two nitrogen donors from two NH3 and two oxygen counter donors from terephthalic acid ligand. The adjacent zigzag chains are arranged in a parallel fashion and linked by interchain hydrogen bonding interaction and π-π stacking interactions into higher-dimensional framework. The compound has also been characterized by CHN elemental analyses, Single crystal X-ray diffraction analysis, powder X-ray diffraction (PXRD) analysis, Fourier transform infrared (FT-IR) spectra, Thermalgravimetric-differential scanning calorimetric (TG-DSC) and Solid-state nuclear magnetic resonance (NMR), etc. Results showed that the framework of compound was stable at the temperature up to 246°C. The desolvated product [Zn (BDC)]n, which was obtained by removal of molecular NH3 from [Zn (NH3)2(BDC)]n, can be transferred to the different skeleton structures through coordinating different small hydrogen-bond-forming molecules.
