Abstract: Two types of sandwich complexes (η5-MeOCH2CH2C9H6) Ln (η8-C8H8) (THF)n [Ln=La (1), Nd(2), n=0; Sm(3), Dy (4) and Er (5). n = l] and (η5-C4H7OCH2C9H6)Ln(η8-C8H8) (THF) [Ln = La (6), Nd(7). Sm(8). Dy (9) and Er (10)] were synthesized by the reactions of LnCl3 with equivalent mole of K2C8H8, followed by treatment with corresponding potassium salt of ether-substituted indenide. The molecular structures of 3 and 8 were determined by single crystal X-ray diffraction. (η5 -MeOCH2CH2C9H6) Sm (η8-C8H8) (THF) (3) monoclinic. Pt1/c, a = 1.4793(3) nm, b = 0.8716 (2) nm, c = 1.6149 (3) nm, β = 98. 17(3), V = 2.0612(7) nm3, Z = 4, R(F)=0.0362. (η5-C4H7OCH2C9H6)Sm(η8-C8H8)(THF) (8) orthorhombic. p212121. a = 0.8754(2) nm, b = 1.1000(2) nm, c = 2.3117 (5) nm, V = 2.2260(8) nm3, Z=4, R(F) =0.0497.
