Abstract: The following complexes were prepared by reaction of anhydrous rare earth trichlorideswith[2,4- (CH3)2C5H5]K and characterized by elmental analysis, IR, NMR, themal analysis,X-ray diffraction analysis as well as chemical analysis of the hydrolysis products: [2,4-(CH3)2C5H5]LnCl2·3THF (Ln = Nd, Sm, Gd), [2,4-(CH3)2C5H5]2LnCl·THF (Ln = Nd, Sm), [2,4- (CH3)2C5H5]3Ln (Ln = La, Sm, Gd),(2,4-(CH3)2C5H5 = 2,4-dimethylpentadienyl; THF = tetrahydrofuran).The complexes are soluble in THF and insoluble in petrolum ether.They are moisture-and air-sensitive.

Key words: dimethylpentadiene, lantanide complexes synthesis
