The complex, (CH 3Cp) 2SmCl·THF, has been synthesized by the reaction of SmCl 3 with two equivalents of CH 3CpNa. (CH 3Cp) 2SmCl·THF crystallized from THF in the rhombic space group P bna with cell constants a=9.662(2), b=16.476(9), c= 20.582(9) ; α=β=γ=90°, V=3276.5 3 ,and D o=1.69g/cm3 for Z=4. Least squares refinement of 2450 unique observed reflections led to a final R of 0.0518. We also compared the structural character of the complex with other trivalent organolanthanide chloride complexes.
