Dimethylformamide. According to conductimetric measurements, europium or terbium nitrates are 2 1 (<0.02 M), or 1 1 (>0.02 M) electrolytes in DMF solutions (Biinzli and Yersin 1982, Biinzli and Vuckovic 1983). Krishnamurthy and Soundararajan (1966) also determined that the first solvation sphere contains one or two nitrato groups. Abrahamer and Marcus (1968) later deduced from the study of the absorption spectra that the R(Ill)/nitrate interaction in DMF was outer-sphere. Finally, using IR, Raman, and electronic absorption spectroscopic data Biinzli and Vuckovic (1984) concluded to inner-sphere R(IIl)/nitrate interaction in DMF solutions. Upon addition of nitrate, equilibria take place which involve mono-, di-, and possibly trinitrato complexes. For [Nd(N03) ] " + and n = 1, the apparent equilibrium ratio is estimated as K 110 30M . A more complicated situation occurs for Eu(lII) (Biinzli and Yersin 1982). Diluted solutions (0.05 M) contain at least three different solvates the predominant...
