Description
The mass spectra of sixty lanthanide chelates of the fluorinated β-diketones RC(OH)=CHCOCF3 (R = 2-theonyl, p-BrC6H4, m-MeC6H4, o-MeC6H4, and Bu-t) have been obtained. The mass spectra were essentially similar, in contrast to those found for d-block transition metal chelates. Valency change from 3 to 2 occurred with samarium (4f5), europium (4f6), thulium (4f12), and ytterbium (4f13); the intensity of the Met(II)-containing peaks varied: Eu >> Sm > Yb > Tm, reflecting the decreasing tendency of these lanthanides to display bivalency. Valency change from 4 to 3 was observed with cerium (4f1) but not with terbium (4f8). (orig.)
