Abstract
|
New supramolecular compound was synthesized from mercury (II) chloride and two ligands (pyridine-2,6-dicarboxylic acid and 2,4-diamino-6-chloropyrimidine) by using sonochemical and side branch tube methods. These compounds were analyzed using FT-IR, TGA-DTA,
1HNMR, 13CNMR, EDS, SEM and TEM. Also, the structures of these complexes were determined by Xray diffraction and crystallography. According to the analyzes performed and the investigations carried out, the compound is a supramolecule with five coordination in the monoclinic crystal system with space group P-1. 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 and N...H) and π-π interactions between aromatic rings such as (C...H, C...C and C. ..N) have a great effect on the stability of the supramolecular structure. Particles of this compound has a rod morphology and the particle size is 200-300 nm.
