✦ Synopsis

The synthesis and spectroscopic characterization of LiLn(allyl),, dioxane (Ln = Ce, Nd, Sm, Gd, Dy) from LnCls and Sn(allyl)4 are described.

The dynamic behaviour of LiSm(allyl), at high and low temperatures was studied and activation parameters were determined. An unusually pronounced broadening of line-width was observed at low temperature for LiNd(allylk and LiCe(ally& complexes.
