| Abstract: | The ligand-exchange equilibria in cyclopentadienyl and metal carbonyl complexes of lanthanum have been qualitatively studied by139La NMR spectroscopy: 2X1X2X3La  X1X2
2 La + X1X3, La, where X1=X2=Cp, X3=I; X1=X2 = 1, 3-(Me3Si)2C5H3, X3=Cl; X1=Ru(CO)2Cp; X2=Cp, X3=I. Similar equilibria are typical of the coordination chemistry of light lanthanides.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 3, pp. 578–581, March, 1993. |
