Abstract
The synthesis and structural characterization of acetonitrile-coordinated Zn(II) and Cu(II) complexes with non-coordinating anions have been systematically investigated. Zinc(II) and copper(II) salts of triflate (OTf⁻), tetrafluoroborate (BF₄⁻), and hexafluorophosphate (PF₆⁻) were employed as starting materials to obtain stable solvated complexes in an acetonitrile medium. The reactions were carried out under strictly controlled solvent purity and temperature conditions to prevent hydrolysis or side processes. The resulting crystalline products were analyzed by infrared (IR) spectroscopy, nuclear magnetic resonance (NMR, for Zn(II)), ultraviolet-visible (UV-Vis) spectroscopy, and electron paramagnetic resonance (EPR, for Cu(II)) to determine coordination modes and ligand-field effects. The study provides insights into the structural preferences of acetonitrile solvates, highlighting the role of non-coordinating anions in stabilizing discrete cationic complexes. These findings are of significance for coordination chemistry, catalysis, and the design of functional molecular materials
