Tetra--chloro-chloro(N,N,N',N'-tetramethylethane-1,2-diamine)(1,1,3-trimethyl-2-imidazolium)dicopper(I)copper(II)

R. J. Butcher, C. George and A. P. Purdy

Abstract: The title compound, [Cu₃Cl₅(C₆H₁₆N₂)(C₆H₁₃N₂)], was isolated from a reaction between Cu(OH)₂, (CF₃)₃COH, C₆H₆, [2-(dimethylamino)ethyl]dimethylamine (TMEDA), and tetrahydrofuran (THF), and contains two inequivalent copper(I) centers as well as a square-pyramidal copper(II) center all linked by ₂-chloro bridges. The 1,1,3-trimethyl-2-imidazolium cation results from the cyclization of a coordinated molecule of TMEDA and contains localized C-N and C=N bonds in contrast to the delocalized C=N bonds observed in other coordinated 1,1,3-trimethyl-2-imidazolium cations.
