S>Step-wise stoichiometric formation constants were determined for the reaction between acetylacetone and the rare earths including yttrium. The measurements were made at a temperature of 30 deg C in 0.1 M aqueous perchlorate. A plot of the logarithm of the first formation constant against the ionic potential shows a linear relation from lanthanum to europium with a change of 0.15 in log K/sub 1/ between consecutive elements. After gadolinium the stability remains nearly constant with a total change in log K/sub 1/ from terbium to lutetium of 0.2. This relation between the ionic potential and log K is compared with the same relation for other rare-earth complexes. (auth)
