Abstract
A new anionic copper(II) complex, (MeImH)(2) Cu(pfbz)(4)] (1) where, MeImH = 2-methylimidazolium and pfbz = pentafluorobenzoate has been isolated by reacting copper(II) sulfate pentahydrate, pentafluorobenzoic acid and 2-methylimidazole in ethanol: water mixture in 1:2:2 molar ratio. This complex 1 has been characterized by elemental analysis, thermogravimetric analysis, spectroscopic techniques (U-VVis, FT-IR) and conductance measurements. The complex salt crystallizes in monoclinic crystal system with space group C2/c. Single crystal X-ray structure determination revealed the presence of discrete ions: Cu(pfbz)(4)](2-) anion and two 2-methylimidazolium cation (C4H7N2)(+). The crystal lattice is stabilized by strong hydrogen bonding and F center dot center dot center dot F interactions between cationic-anionic and the anionic -anionic moieties respectively, besides pi-pi interactions.
