University of Basra discusses a master’s thesis on (preparation and theoretical study of some new complexes of copper (ll) and cobalt (ll))
My master’s thesis, Department of Chemistry at the College of Education for Pure Sciences at the University of Basra, discussed the preparation and theoretical study of some new complexes of copper(ll) and cobalt(ll).
The message submitted by the researcher (Jaafar Hassan Zaghir) included:
Preparation of ligand (L), which is one of the carbonylthiourea derivatives, from the reaction of 4-nitrobenzoyl chloride with potassium thiocyanate, then reacting the product with (2,4,6-trichlorophenyl)hydrazine. The correct molecular structure of this compound was proven by diagnosing it using resonance spectra. Proton nuclear magnetic (1H-NMR), carbon (13C-NMR) and FT-IR spectroscopy. The prepared compound was used as a ligand in preparing coordination complexes with copper(II) ion and cobalt(II) ion by reacting this ligand with aqueous copper(II) chloride salt and aqueous cobalt(II) chloride in a molar ratio of 2:1 [metal: ligand]. The prepared complexes were characterized using infrared spectroscopy (FT-IR) and thermogravimetric analysis (TG). The molar conductivity and magnetic susceptibility of the complexes were studied.
The research included the preparation of a ligand derived from 4-nitrobenzoyl chloride and (2,4,6-trichlorophenyl)hydrazine, as well as the preparation of new coordination complexes using the ligand prepared with copper (II) ion and cobalt (II) ion. The prepared ligand was characterized by diagnostic methods such as IR, 1H-NMR, and 13C-NMR, and the complexes were diagnosed by spectroscopic methods (FT-IR), thermal, and magnetic susceptibility, in addition to conductivity measurements. The research included studying some of the electronic and energy properties of the prepared compounds using computational chemistry.
