SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF Cu(II) WITH HEXAMETHYLENTHIOSEMICARBAZONE LIGAND CONTAINING PYRENE

Abstract

     The ligand H-7CPTSC was synthesized by condensation reaction between 1-pyrandehyde and relevant thiosemicarbazide. The complexation of the ligand with cooper ion occurred in aqueous ammonia solution. Using different physical methods such as infrared spectroscopy, nuclear magnetic resonance spectroscopy, mass spectrometry, and X-ray single crystal diffraction, it is confirmed that the ligand and its copper complex have been successfully synthesized. Also, the complex shows a metal:ligand ratio is of 1:2.

Keywords: thiosemicarbazone, pyrene, copper, metal complex, X-ray structure.
