The dynamic ~ 1H and ~ (13) C-NMR studies on [Li (2D)] [Nd (η ~ 8-C_3H_5) _4] (D = dioxane) areequivalent 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 characterization of η ~ 2 = -allyl. The paramagnetic shifts of carbons in allylsinduced by Nd ~ (2+) ere separated sucessfully.C_1 and C_3 located on thezero-dipolar cone.The content of contact shift is greater than that of dipolarslift to Co.
