characterized in solution and the solid state. Single crystal structures of [Cu(POP)(1)][PF6], [Cu(xantphos)(1)][PF6], [Cu(xantphos)(2)][PF6], [Cu(POP)(3)][PF6]·CH2Cl2, and [Cu(xantphos)(4)][PF6] confirm chelating N^S and P^P ligands, and distorted tetrahedral copper(I) centres. There is close cation⋯anion association, particularly in [Cu(xantphos)(1)][PF6]. Although the compounds are stable over days in CH2Cl2
