Three Cu(II) complexes of the (R,R)-N,N'-bis(3,5-di-tert-butyl-2-aminobenzylidene)-1,2-diaminocyclohexane ligand, [Cu(NL)], [Cu(NLH)]⁺ and [Cu(NLH₂)]²⁺, were prepd. and structurally characterized. In [Cu(NLH₂)]²⁺ the Cu ion lies in an octahedral geometry with the aniline groups coordinated in equatorial positions. In [Cu(NL)] the anilines are deprotonated (anilido moieties) and coordinated to an almost square-planar metal ion. [Cu(NL)] displays two oxidn. waves at E_1/2ox.
