Effect of sodium acetylacetonate on the transition of scandium and lutecium acetylacetonates to the gas phase

It was shown by preparative chemistry, IR spectroscopy X-ray powder diffrac tion and thermal analyses, and vacuum sublimation that the reaction of sodi um acetylacetonate monohydrate with tris(acetylacetonato)lutecium results i n the formation of tetrakis(acetylacetonate) NaLu(Acac)(4), which is capabl e of subliming congruently in vacuo. This effect is not observed in the sys tem with scandium. The sublimation of sodium acetylacetonate as a constitue nt of the lutecium tetrakis complex can be regarded as a synergism, because sodium acetylacetonate itself is nonvolatile.
