Abstract
The ligand-exchange equilibria in cyclopentadienyl and metal carbonyl complexes of lanthanum have been qualitatively studied by La-139 NMR s pectroscopy: 2X1X2X3LA half arrow right over left X1X2(2)La + X1X3(2)L a, 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 c oordination chemistry of light lanthanides.
