Abstract

This study is concerned with the polarographic behavior of several tetrakis 1, 3-diketone chelates of europium and of the 1, 3-diketone ligands in acetonitrile. Such a study should reveal the following: (a) whether the europium (III) in the complexes is reduced directly to the metal, or if reduction to europium (II) takes place followed by reduction to the metal; (b) whether ligands are released during the reduction step(s) and if so, how many; (c) whether the polarographic behavior is such that dissociation constants of the complexes or complex ions can be determined by measuring the shift in half-wave potential as a function of the ligand concentration; and (d) whether the ligands are reduced at a more positive potential than the europium. Should the reduction steps include the formation of a europium(II) chelate, this method could be exploited for the electrosynthesis of such chelates. Studies of the spectra and laser phenomena of these chelates have shown that solvent-ligand interactions affect the dissociation of the tetrakis form of the chelates (1-7). It would be interesting to see if there is any correlation between the polarographic behavior of these chelates and the effects of the solvent-ligand interactions.

Carstens by which the polarograph used in this study was built.
