Sodium β-Diketonate Glyme Adducts as Precursors for Fluoride Phases: Synthesis, Characterization and Functional Validation.

Very few sodium complexes are available as precursors for the syntheses of sodium-based nanostructured materials. Herein, the diglyme, triglyme, and tetraglyme (CHO(CHCHO)CH, = 2-4) adducts of sodium hexafluoroacetylacetonate were synthesized in a single-step reaction and characterized by IR spectroscopy, H, and C NMR. Single-crystal X-ray diffraction studies provide evidence of the formation of the ionic oligomeric structure [Na(hfa)]•2[Na(diglyme] when the diglyme is coordinated, while a mononuclear seven-coordinated complex Na(hfa)•tetraglyme is formed with the tetraglyme.

Facile synthesis of novel lithium β-diketonate glyme adducts: the effect of molecular engineering on the thermal properties.

Novel adducts of lithium hexafluoroacetylacetonato {Li(hfa)} with polyethers (monoglyme = {CHOCHCHOCH}, diglyme = {CHO(CHCHO)CH}, triglyme = {CHO(CHCHO)CH} and tetraglyme {CHO(CHCHO)CH} have been synthesized through a single step reaction and characterized by FT-IR spectroscopy, H, and C NMR, single crystal X-ray diffraction studies along with thermal analysis.
