Copper(I) and copper(II) complexes of the ligand N , N ′‐bis[2′(dimethylamino)ethyl]‐ N , N ′‐dimethylethane‐1,2‐diamine (Me 6 trien) were synthesized and structurally characterized. In the solid state the complex cation [Cu(Me 6 trien)] + ( 1 ) adopts a distorted tetrahedral configuration. Crystallography, EPR measurements, and UV/Vis spectroscopy indicate that the analogous copper(II) complex [Cu(Me 6 trien)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.
