- Аннотация: Based on salts Na+[Ln3+(C5HF6O2)4]−, where Ln3+= Er3+(1), Ho3+(2), Dy3+(3), and hexafluoroacetylacetone (C5HF6O2), and using metathesis reactions, salts with an organic dication 1,1′‑diethyl-4,4′-dipyridinium (C14H18N22) of general composition C14H18N222+[Ln3+(C5HF6O2)4]−2, where Ln3+=Er3+ (4), Ho3+(5), Dy3+(6) have been synthesized for the first time and characterized by X-ray analysis, IR spectroscopy and magnetometry. The effect of the nature of the rare earth metal (3+) and the dication size on the magnetic sublattice in salts 4–6 has been analyzed. It has been shown that an organic counterion can be used for tuning the coordination geometry and magnetic dynamics in the salts with [Ln3+(C5HF6O2)4]− anion.
