Coinage-metal complexes are of modern interest in all fields of Chemistry due to their
fascinating applications. Particularly, coordination polymers composed of Gold, Silver, or
Copper (+1)-cations with organic molecules to form sophisticated mono-ligand or mixedligand
coordination polymers capable of photophysical properties like absorbing or
emitting light, or forming metal-organic-frameworks that can store various molecules
like benzene or ammonia for storage and separation. In this research, copper
acetonitrile and quinoxaline complexes with the formula
[Cu(CH3CN)y(Quinoxaline)x]BF4 were synthesized with variations in the molar ratios.
Green syntheses were conducted using mechanical grinding to reduce the usage of
traditional solvents. Typically reactions require environmentally hazardous organic
solvents. For this reason, Green Chemistry principles of seeking more environmentallyfriendly
alternatives to create equally-efficient compounds are used. Comparisons and
characterizations were made of the several products from various techniques like
melting point, Fourier-Transform Infrared Spectroscopy (FTIR),Thermogravimetric
Analysis (TGA), and Spectrofluorometry.
