文摘The dynamic ~1H and ^(13)C-NMR studies on [Li(2D)][Nd(η~8-C_3H_5)_4] (D=dioxane)were reported The four allyls coordinated to Hd^(8+) ion are equivalent and hydrogens appear as three groups in ~1H-NMR spectra with their chemical shifts changing with temperature.C_1 and Ca are equivalent showing the characteristic of η~2=-allyl.The paramagnetic shifts of carbons in allyls induced by Nd^(2+) ere separated sucessfully.C_1 and C_3 located on the zero-dipolar cone.The content of contact shift is greater than that of dipolar slift to Co.
