Abstract
X-ray structural analysis of a samarium triscyclopentadienyl complex, Cp3Sm . OC4H8 (1), and a samarium ionic salt, [Li(Et2O)2][CP3SM(mu-Cl) SmCp3] (2), was carried out. In both compounds coordination saturation is achieved by coordination of the THF molecule (in 1) or the Cl- ani on (in 2) to the monomeric fragment CP3Sm. An unusual coordination of the Li+ cation was observed in complex 2: it is bound to one of the et a5-type cyclopentadienyl rings in addition to two ether molecules.
