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

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 A) and two tri­fluoro­methyl­sulfonate anions at the axial sites, with long Cu—O bonds of 2.651 (4) and 3.069 (6) A; thus, the Cu atom has the octahedral environment typical for CuII complexes, with a tetragonal distortion. All four 2-methyl­imidazole rings are tilted out of the CuN4 plane by about 50°.
