title: {2,2-Bis[(4S)-4-tert-butyl-4,5-dihydro-1,3-oxazol-2-yl]propane}bis-(N,N-di-methyl-formamide)copper(II) bis-(hexa-fluoridoantimonate).
abstract: In the title compound, [Cu(C(17)H(30)N(2)O(2))(C(3)H(7)NO)(2)][SbF(6)](2), which is a potential catalyst in the asymmetric Gosteli-Claisen rearrangement, the Cu atom adopts a distorted cis-CuN(2)O(2) square-planar geometry arising from N,N'-bidentate coordin-ation by the chiral ligand and two O-bonded dimethyl-formamide mol-ecules. Two short C-H⋯O contacts occur within the ligand and two weak inter-molecular C-H⋯F bonds may help to establish the packing.
