Abstract

Copper(I) and copper(II) complexes of the ligand N,N'-bis[2'- (dimethylamino) ethyl] -N,N'-dimethylethane-1,2-diamine (Me6trien) were synthesized and structurally characterized. In the solid state the complex cation [Cu(Me6trien)]+ (1) adopts a distorted tetrahedral configuration. Crystallography, EPR measurements, and UV/Vis spectroscopy indicate that the analogous copper(II) complex [Cu(Me6trien)Cl]+ has a square pyramidal geometry in the solid state as well as in solution. The reaction of 1 with dioxygen was investigated in different solvents. No copper dioxygen intermediates could be detected spectrophotometrically during these reactions.
