Synthesis and Characterization of Mercury(II) SupramolecularCompoundfromPyridine-۲,۴-dicarboxylic acid

New supramolecular compound was synthesized frommercury (II) chloride and two ligands(pyridine-۲,۶-dicarboxylic acid and ۲,۴-diamino-۶-chloropyrimidine) by using sonochemical andside branch tube methods. These compounds were analyzed using FT-IR, TGA-DTA,۱HNMR,۱۳CNMR,EDS, SEM and TEM. Also, the structures of these complexes were determined by Xraydiffractionand crystallography. According to the analyzes performed and the investigationscarried out, the compound is a supramolecule with five coordination in the monoclinic crystalsystem with space group P-۱. By examining the angles and bond lengths around the central atom,a distorted square pyramidal geometric shape has been proposed for this compound.Also,intermolecular and intramolecular interactions that include hydrogen bonds such as (O...H andN...H) and π-π interactions between aromatic rings such as (C...H, C...C and C. ..N) have a greateffect on the stability of the supramolecular structure. Particles of this compound has a rodmorphology and the particle size is ۲۰۰-۳۰۰ nm
