Studies on Organolanthanide Complexes. 53. Effect of Rare Earth Metal Radius on the Molecular Structure: Synthesis and X-ray Crystal Structure of Bis((2-methoxyethyl)cyclopentadienyl) Rare Earth metal Chlorides

Chemical preparation and X-ray diffraction determined crystal structures of (CH{sub 3}OCH{sub 2}CH{sub 2}C{sub 5}H{sub 4}){sub 2}LnCl [Ln = La (1), Pr (2), Nd (3), Sm (4), Gd (5), Dy (6), Ho (7), Er (8), Tm (9), Yb (10), Lu (11), Y (12)] are reported. Further characterization by elemental analysis, MS, NMR, and IR spectroscopy was performed for these complexes. From these data, the molecular structures are described.
