摘要：

Steric factors govern the formation of half-sandwich complexes (C5Me4R)Ln[N(SiHMe2)(2)](2) according to acid-base reactions utilising Ln[N(SiHMe2)(2)](3)(thf)(2) and substituted cyclopentadienes. Subsequent trimethylaluminium-promoted silylamide elimination produces the first half-sandwich bis(tetramethylaluminate) complexes (C5Me4R)Ln(AlMe4)(2).
