Abstract
Das THF-Addukt des Decamethylsamarocens, Cp2 Sm(THF)2, reagiert mit Disulfiden, Diseleniden und Ditelluriden zu Organosamarium(III)komplexen, die eine Sm–E-Bindung enthalten (E = p. Se, Te). Die Molekülstrukturen der Komplexe Cp2 Sm(S2CNMe2) (1), Cp2 Sm[TeC6H2Me3-2,4,6](THF) (4) und Cp2 Sm[SeC6H2(CF3)3-2,4,6](THF) (5) wurden röntgenographisch bestimmt. Abstract: The THF adduct of decamethylsamarocene, CP2Sm(THF)2, reacts with disulfides, diselenides and ditellurides to give organosamarium(III) complexes containing a Sm---E bond (E = S, Se, Te). The molecular structures of the complexes CP2Sm(S2CNMe2) (1), Cp2Sm[TeC6H2Me3-2,4,6](THF) (4) and Cp2Sm[SeC6H2(CF3)3-2,4,6](THF) (5 have been determined by X-ray diffraction.
