A One-Pot Synthesis of “K(hfa) glyme” Adducts: Effect of the Polyether Length on the Ion Coordination Sphere

Potassium complexes are starting to gather more and more interest from academia and industry because of their intriguing application possibilities. Novel adducts of potassium hexafluoroacetylacetonato [K(hfa)] with polyethers (monoglyme, diglyme, triglyme, and tetraglyme) were synthesized through a single step reaction and characterized through FT-IR spectroscopy as well as 1H and 13C NMR spectroscopy. Single crystal X-ray diffraction studies enabled the identification of fascinating K coordination polymeric networks.
