Metallorganische verbindungen der lanthanoide: XXXI. Synthese und molekülstruktur einiger cyclopentadienyllutetiumhydride☆

Abstract The reaction of alkyl- and aryl-(dicyclopentadienyl)lutetium complexes ( 1 ) with H 2 or D 2 gives dimeric dicyclopentadienyllutetiumhydride ( 2 ) or -deuteride ( 3 ). Dicyclopentadienyllutetiumchloride ( 4 ) reacts with sodium in tetrahydrofuran (THF) with formation of [Na(THF) 6 ][(Cp 2 LuH) 3 H] ( 5 ). Tricyclopentadienyllutetium ( 6 ) reacts with NaH or NaD to give the complexes [Na(THF) 6 ][(Cp 3 Lu) 2 H]·2(THF) ( 7 ) or [Na(THF) 6 ][(Cp 3 Lu) 2 D]·2(THF) ( 8 ), respectively. The molecular structures of 2 and 7 were determined by single crystal X-ray diffraction.
