Supramolecular Frameworks of Zinc-Pyridine-۲,۶-dicarboxylic acidCompound: Synthesis and Characterization

New Zinc-Pyridine-۲,۶-dicarboxylic acidsupramolecular compound was synthesized fromzinc chloride and two ligands (pyridine-۲,۶-dicarboxylic acid and ۲,۴-diamino-۶-chloropyrimidine) by using sonochemical and side branch tube methods. The compounds werecharacterized by X-ray diffraction and crystallography, FT-IR, XRD, TGA-DTA, ۱HNMR,۱۳CNMR, EDS, SEM and TEM techniques. The compound is a supramolecule with fivecoordination in the monoclinic crystal system with space group P۲۱/c. By examining the anglesand bond lengths around the central atom, a distorted square pyramidal geometric shape has beenproposed for the compound. Non-covalent intermolecular forces have a great contribution increating the supramolecular structure of this compound. Intermolecular and intramolecularinteractions, including hydrogen bonds such as (O...H) and π-π interactionsbetween aromaticringssuch as (C...H, C...C, N...H and C...N). Particles of this compound has a cubicmorphologyand the particle size is ۳۰۰-۵۰۰ nm
