Synthesis and Characterization of Mononuclear Cobalt(II) and BinuclearCopper(II) Complexes with Tetradentate Ligand(L)

This research describes the synthesis and charactrization of new mononuclear cobalt(II) andbinuclear copper(II) complexes with the tetradentate ligand: N,N'-bis(ortho-carbonyl, benzoicacid) ۱,۳-diaminopropane dihydrochloride (L), which is divided into the following two parts: Inthe first part, the ligand (L) is synthesized from the reaction of trimethylene diamine compound(tn) with phthalic anhydride and then partial hydrolysis of its product using alkaline sodiumhydroxide solution, under completely controlled conditions, which is similar to the synthesis ofSchiff base ligands. In the second part, by the McCarthy method, two complexes [Co(L)(H۲O)۲]and [Cu۲(L)(MeO)۲(MeOH)۲] are synthesized using this ligand and salts of cobalt(II) nitratehexahydrate and copper(II) nitrate trihydrate in methanol solvent and pH adjustment by sodiummethoxide. The structure of the synthesized products has been characterized through the analysisof spectra obtained from IR, FT-IR, ۱H NMR, ESR spectrometers, as well as the results ofelemental analysis, and the study of their electron absorption spectrum has been done by UV-Visdevice.
