Background: single crystal and Sediment of Copper(II) and Cobalt(II) supramolecular, [Cu(L)(L')(H2O)].H2O (1) and [Co(L)2].(L').(H2O). (2) (L = Pyridine-2,6- dicarboxylic acid, L' = 2,4-diamino-6-chloropyrimidine) ligands, have been synthesized by side branch tube and sonochemical methods.
Aim: Synthesis and characterization of supermolecule compounds is the new goal of this project.
Methodology: The new compounds were characterized by X-ray diffraction and crystallography, FT-IR, XRD, TGA-DTA, and SEM techniques. The Hirshfield surfaces of compounds crystal packing and the fingerprint maps were used to obtain data regarding non-covalent interactions.
Conclusions: Single crystal X-ray diffraction showed that mononuclear Copper(II) compound (1), was synthesized by side branch tube method and crystalized in monoclinic crystal system and in Space Group P21/c. The compound was characterized by X-ray diffraction and crystallography, FT-IR, XRD, techniques. The coordination environment of Copper(II) ion is five. A Hirshfeld surface and topological analysis of compound (1) was carried out. intramolecular interactions, including hydrogen bonds such as (O...H, H…H ) and π-π interactions between aromatic rings such as (C...H, C...C and C...N). Powder of compound (1') was synthesized by the sonochemical method were characterized by XRD, scanning electron microscopy (SEM), IR spectroscopy and EDS and thermogravimetry methods. Debye-Scherrer method determined the mean of powder size to be 100-200 nm. Compound (2) was crystalized in monoclinic crystal system and in Space Group C2/c, and structurally characterized by single crystal X-ray diffraction. The crystal structure of compound (2) show the relevant coordination number for the Cobalt(II) ions are found to be six. A Hirshfeld surface and topological analysis of compound (2) was carried out. By examining the bond angles and bond lengths around the central atom, a octahedral geometric shape has been proposed for this compound.
