  The crystal of Cp3′Sm (II) belongs to the monoclinic crystal system, space group P21/n with a = 8.415(7), b = 20.439(3), c = 12.926(2) Å, β = 90.34(3)°, V = 2223.2 Å3, Dcalcd = 1.562 g cm−3 and Z = 4. The three Cp′ ring centroids and two oxygen atoms of Cp′ describe a trigonal bipyramid around the central ion of samarium. Complexes I, II and III are all unsolvated monomeric molecules with higher coordination

  solvent-free organolanthanide complexes (MeOCH2CH2C5H4)2SM (1) and (MeOCH2CH2C5H4)2Yb (2) have been synthesized by the interaction of (MeOCH2CH2C5H4)K with LnI2(Ln = Sm, Yb). Recrystallization of 2 from THF produced the solvated single crystal (MeOCH2CH2C5H4)2Yb·OC4H8 (3) which has the coordination number of nine, the highest yet reported for this class of compound. The two ring centroids of the 2-methoxyethylcyclopentadienyl

  The partial hydrolysis of Cp'2ErCl (1) (Cp' = CH3OCH2Ch2C5H4) affords [CP'2Er(mu-OH)]2, the single crystal X-ray structure of which reveals that the complex is dimeric with bridging hydroxide groups. The molecular structure shows the hydroxyl groups bridging with distances Er-O = 2.258(5), 2.216(5) angstrom, and the methoxyethyl group coordinating with distances Er-O(1) = 2.542(3), Er-Cp1 = 2.3981(4) and Er-Cp2 = 2.1680(3) angstrom. The bond angles of O-Er-O* and O-Er-O(1) in 2 are 71.6(2) and 73.2 (2)-degrees, respectively.

  LnCl(3) reacted with K2C8H8 in THF in the ratio 1:1 at room temperature and formed (C8H8)LnCl . nTHF, which was then treated with RCpK-THF (RCp = MeOCH2CH2C5H4 or C4H7OCH2C5H4) to yield the title complexes (eta(5)-RCp)Ln(eta(8)-C8H8) (THF) (Ln = Nd (1) and Sm (2), RCp = MeOCH2CH2C5H4; Ln = La (3), Nd (4) and Sm (5), RCp = C4H7OCH2C5H4). The crystal structures of complexes 1 and 3 were determined by X-ray diffraction and revealed that the oxygen atoms of the ether group on the cyclopentadienyl ring is coordinated to the central metal atom. The central lanthanum atom is in a distorted tetrahedral geometry. The average bond distances Nd-C(eta(8)) and Nd-C(eta(5)) are 2.697(2) and 2.749(2) Angstrom, respectively, while the Nd-O(THF) and Nd-O(eta(1)) distances are 2.580(1) and 2.619(1) Angstrom, respectively. The average bond lengths La-C(eta(5)) and La-C(eta(8)) are 2.842(7) and 2.740(8) Angstrom, respectively. The La-O(THF) and La-O(eta(1)) distances are 2.607(4) and 2.633(4) Angstrom.
