Unsolvated hydride derivatives [Me 2 Si(2‐Me‐C 9 H 5 ) 2 LnH] (Ln=Y, Ho) are available from ansa ‐lanthanidocene complexes rac ‐[{Me 2 Si(2‐Me‐C 9 H 5 ) 2 }Ln{N(SiHMe 2 ) 2 }] by utilizing a novel [N(SiHMe 2 ) 2 ]/[H] transformation inititated by diisobutylaluminumhydride (DIBAH; see scheme; R=SiHMe 2 ). The molecular structure of the THF adduct reveals a “flyover” dimer of composition [{Y(thf)} 2 {μ 2 ‐[(η 5 ‐2‐Me‐C 9 H 5 )SiMe 2 (η 5 ‐2‐Me‐C 9 H 5 )]} 2 (μ 2 ‐H) 2 ].
