A Copper(II) Complex of a New Chiral Tridentate Imidazoline Ligand

The title compound, {2,6-bis[(4R,5R)-1,3-dimethyl-4,5-diphenylimidazolidin-2- yl-N¹]pyridine-N}chlorocopper(II) hexafluorophosphate 0.5-methanol solvate, [CuCl(C₃₉H₄₁N₅)]PF₆.0.5CH₃OH, is the first example of a metal complex containing the new chiral ligand, 2,6-bis[(4R,5R)-1,3-dimethyl-4,5-diphenylimidazolidin-2-yl]pyridine. Complexation of the ligand to the Cu atom results in only a slight distortion from idealized C₂ symmetry in the crystal in spite of its less symmetrical environment.
