We have isolated the complexes of the Schiff bases N-(4-methyl-2-pyridyl)salicylaldimine and N-(6-methyl-2-pyridyl)salicylaldimine with Co(II), Ni(II), Cu(II), and UO2(II) in both aqueous alcoholic and absolute alcoholic solutions. We note different modes of action of these Schiff bases according to the medium used. However, in aqueous alcoholic solution the complexes mentioned have a remarkable capacity for reaction with the substances in solution. We propose two new gravimetric methods for Ni(II) and UO2(II).

Chemical Behaviour

The lanthanide chelates MetL3,nH2O (Met = Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, or Yb; L = PhCO= CHCOCF3, p-MeC6H4CO=CHCOCF3, p-MeOC6H4CO=CHCOCF3; n = 2, 3 or 1) have been isolated. The conditions were found to be critical, involving the slow addition of an ammoniacal aqueous alcoholic solution of the β-diketone to an excess of the lanthanide nitrate solution while the pH was maintained within the range 6.0-6.5. The mass spectra of most of the chelates were obtained and were essentially similar and fluorine migration to the metal was found to occur. Although a peak for the ion M-L (M = MetL3+) is present in the spectra, peaks for M-2L and M-3L are absent; however, peaks were obtained for the ions M-2L+ F and M-3L+2F (Met111F2). A peak for the ion M- L+ F (Met11F) was obtained when Met = Sm, Eu and Yb. The valency change from 3 to 2 occurring in the mass spectrometer in the case of samarium, europium and ytterbium is in accordance with their chemical behaviour in solution.
