>The capacity of rare earth elements to form complex compounds was studied with 59 organic and inorganic agents. Experiments confirmed the ability of rare earths to combine into complex compounds and showed that as a rule their capacity to combine improves with decreasing ionic radii. The coordinate number of rare earth elements in trivalent state in most cases equals six. Tetravalent Pr and Ce and in some cases divalent Eu and Sm form complex compounds. However, in contrast to such active metals as Pt, Pd, Fe, and Co the rare earth elements do not form stable complex compounds with Cl/sup 0/, NH/sub 3/, CNand NO. The most stable compounds were formed with organic groups. The stability of the complexes with organic acids depended on the base and structure of the acid. (R.V.J.)
