Abstract: In the title compound, [Cu(C₁₇H₃₀N₂O₂)(C₃H₇NO)₂][SbF₆]₂, which is a potential catalyst in the asymmetric Gosteli-Claisen rearrangement, the Cu atom adopts a distorted cis-CuN₂O₂ square-planar geometry arising from N,N'-bidentate coordination by the chiral ligand and two O-bonded dimethylformamide molecules. Two short C-HO contacts occur within the ligand and two weak intermolecular C-HF bonds may help to establish the packing.
