摘要：

By the one-pot reaction of lanthanide trichloride with 2 equivalents of sodium cyclopentadienyl and 1 equivalent of sodium 2-methoxyethylcyclopentadienyl in THF, the mixed tricyclopentadienyl lanthanide complexes (C5H5)2Ln(CH3OCH2CH2C5H4) (Ln = La, Sm, Gd, Er, Yb, Y) were obtained. The compound (CH3OCH2CH2C5H4) Y(C5H5)2 (6) crystallized from THF. The central metal Y is coordinated to three cyclopentadienyl ring centroids and the ether oxygen forming a distorted tetrahedron. The average Y-C(eta5) bond distance and Y-O bond distance of 6 are 2.702 and 2.414 angstrom, respectively.
