Popis: The coordinated tetrahydrofuran in (MeC 5 H 4 ) 3 Ce(THF) can be removed by Me 3 Al in a Lewis acid-base reaction or by the «toluene-reflux method» to give base-free (MeC 5 H 4 ) 3 Ce which is a monomer in the gas phase though a tetramer in the solid state: monoclinic, P2 1 /a, with a=12.497 (5) A, b=26.002 (8) A, c=9.664 (3) A, β=97.32 (3) o ; R=0.041 for 2117 data, F 2 >2σ(F 2 )
