Condensed dialkoxide complex of copper(II), [(CH3)2 NCH2CH2N(CH3)2]-Cu[{OC (CF3)2}2O]

The title complex, [1,1,1,5,5,5-hexafluoro-3-oxa-2, 4-bis(trifluoromethyl)-2,4-pentanediolato-O,O′]- (N,N,N′, N′-tetramethylethylenediamine-N,N′)copper(II), [Cu(C6F12O3)(C6H16N2)], contains a condensed dialkoxide ligand forming a markedly non-planar six-membered chelate ring with a skew-boat conformation. There are two independent molecules in the unit cell. In molecule 1, the absolute conformations of the tetramethylethylenediamine and dialkoxide rings are both λ and in molecule 2, they are δ and λ, respectively. The mean O - Cu - O angle is 92.6 (3)°, with a mean Cu - O bond length of 1.893 (3) angstrom.
