Rare earth acetylacetonates: New preparative methods and new complexes

Add time:09/07/2019    Source:sciencedirect.com

New preparative methods have been developed and used to prepare several new rare earth acetylacetonate complexes. Crystalline forms of anhydrous neodymium and europium trisacetylacetonate and amorphous forms of anhydrous lanthanum, neodymium, samarium, europium, gadolinium and terbium trisacetylacetonates are reported. Monobasic derivatives of the neodymium and europium complexes were also prepared. Spectral, physical and chemical properties of the complexes are described. Marked differences in the properties of the crystalline and amorphous anhydrous compounds were observed.
