- Аннотация: Chelating sulfur-containing cyclopentadienyl ligand tetramethyl(2-methylthioethyl)eyclopentadiene (1), was synthesized for the first time. Its sodium (2a) and lithium (2b) derivatives were isolated in the crystalline state. Starting from compotmd 1 some novel Zr(IV) complexes were prepared: [tetramethyl(2-methylthioethyl)cyclopentadienyl]trichlorozirconium (3), bis[tetramethyl(2-methylthioethyl)cyclopentadienyl]dichlorozirconium (4), and [pentamethylcyclopentadienyl][tetramethyl(2-methylthioethyl)cyclopentadienyl]dichlorozirconium (5). The crystal structures of 3 and 5 were determined by X-ray diffraction analysis. The dynamic behavior of complex 3 in various solvents was investigated by 1H and 13C NMR spectroscopy. The S-->Zr coordination bond was shown to exist in complex 3 both in the crystalline state and in solution. No coordination of this type was found in compounds 4 and 5.
