Alkylisocyanide complexes of copper(I) with formula [Cu(CNR)₄]BF₄ [where R = 2-methoxyisobutyl and 2-(carbomethoxy)-2-methylethyl] were synthesized by direct reaction of cuprous chloride with ligand. The stability of solid complexes and their aqueous solutions were tested by HPLC. Comparative studies were carried out on electronic. IR and ¹H NMR spectroscopy. Crystal structures of [Cu(MIBI)₄]BF₄ and [Cu(CPI)₄]BF₄ were determined from X-ray data and show a tetrahedral arrangement of ligands around the central copper atom in both compounds.
