Tetrakis(2-methylimidazolo)bis(trifluoromethylsulfonato)copper(II)

S.-J. Liu, R.-J. Wang and C.-C. Su

Abstract: The title complex, [Cu(C₄H₆N₂)₄(CF₃SO₃)₂], was prepared by reaction of Cu(CF₃SO₃)₂·6H₂O and 2-methylimidazole in acetonitrile. The central Cu atom is coordinated by four 2-methylimidazole ligands forming an equatorial plane (average Cu-N 2.007  Å) and two trifluoromethylsulfonate anions at the axial sites, with long Cu-O bonds of 2.651  (4) and 3.069  (6)  Å; thus, the Cu atom has the octahedral environment typical for Cu^II complexes, with a tetragonal distortion. All four 2-methylimidazole rings are tilted out of the CuN₄ plane by about 50°.
