This study aimed to compare the stability, physical, and chemical attributes of Cu(I) and Cu(ACN) metals, investigating their resemblances and disparities. It comprises approximately 137 pages, encompassing 90 figures, 16 tables, and references. The research focused on synthesizing and characterizing Cu(I) complexes with azole family ligands. Two methodologies were applied: the first involving CuI and Cu(CH3CN) (where X = I or CH3CN) reacting with single ligands like 3,5-diisopropylpyrazole, 3,5-diphenolpyrazole, 3,5-(tert)-butylpyrazole, and 5-(4-chlorophenyl)-1H-tetrazole. The second utilized Cu(CH3CN) with mixed ligands specifically 3,5-diphenolpyrazole and pyrazine, as well as 3,5-(tert)-butylpyrazole and pyrazine. Complex synthesis occurred via solvent-mediated routes using the Schlenk technique and solvent-free reactions with mechanical grinding. Comprehensive characterization involved techniques such as melting point determination, solubility tests, luminescence spectroscopy, FT-IR, TGA, elemental analysis, NMR, and X-ray crystallography. Ligands were characterized using the same listed techniques to understand changes. All synthesized products underwent thorough characterization using diverse analytical tools.
