What is The formation and x-ray crystal structure of (η5-C5H5)2LuCl · OC4H8 about?

LuCl, reacts with two equivalents of sodium cyclopentadienide in THF followed by crystallization from this solvent at 5°C to afford (C,H,),LuCl. OC,H,. The product has been characterized by its proton NMR and mass spectra, elemental analysis and by single crystal X-ray diffraction studies. The complex (C,H,),LuCl . OC,H, crystallizes in the monoclinic space group P2,/n with the unit cell parameters, a 8.116( ), b 12.670(2), c 14.376(l) A, fi 10561(l)", I/ 1423.7 A3, Z = 4, DC 1.925 g cmp3. The structure was solved by heavy-atom Patterson techniques and the least-squares refinement has led to a final R value of 0.097 based on 2253 independent observed reflections. The THF molecule is coordinated to the lutetium atom at a Lu-0 bond length of 2.27(l) A. The Lu-C(n5) bond distances average 2.56 A. The compound ($-C,H,),LuCl . OC,H, is a neutral monomer.
