Descrição: The synthesis, spectroscopic and structural characterization of new amido-fluorenyl ligand [{Me 3CN(H)Si(Me) 2CH 2C 3H 8}Li(THF)] ( 1) is reported. The treatment of 1 with BuLi followed by the reaction with Group 4 metal chlorides led to crystalline, solvent free, metal complexes [{( η 1−NCME 3)Si(Me) 2CH 2( η 5−C 13H 8)}MCl 2] ( where M = Ti ( 3), Zr ( 4) or Hf ( 5) ) in good yield. The X-ray crystal structures of 4 and 5 are also reported. Both these compounds possess monomeric structures with relatively short MN and MCl bonds. The MN distances of 4 and 5 are 2.060(3) Å and 2.065(3) Å respectively. The metal ion is coordinated to the fluorene group in η 5-fashion. The X-ray data also indicate the presence of a relatively unstrained ligand backbone in these metal complexes.
