  摘要：

  The dimeric complexes [(COT)Ln(mu-O3SCF3)(THF)2]2 (Ln = Ce (1), Pr (2), Nd (3), Sm (4)) are easily prepared by treatment of anhydrous lanthanide(III) triflates with equimolar amounts of K2COT (COT = eta8-cyclooctatetraenyl(2-)). The reaction of lanthanide triiodides with K2COT affords monomeric complexes of the type (COT)Ln(I) (THF)3 (Ln = Nd (5), Sm (6)). Due to their increased solubility in polar organic solvents these new precursors offer preparative advantages over the previously used chloro derivatives [(COT)Ln(mu-Cl)(THF)2]2. The molecular structures of 3 and 5 have been determined by X-ray diffraction.

  The reaction of neodymium diiodide NdI2 (1) With acetonitrile is accompanied by C-C coupling and formation of bis(ethylimine)ethylamine/acetonitrile complexes [(MeC=NH)(2)CMeNH2]NdI(MeCN)(5)}I-2 (2) and [(MeC=NH)(2)CMeNH2]Nd(MeCN)(6)}I-3 (3). Yields of the products are 9% and 50%, respectively. Probable scheme of the complexes formation is discussed. Treatment of 3 with 2 equiv. of 1 in THF affords NdI3(THF)(3), hydrogen and monoiodide complex containing presumably bis(imide)amine ligand, NdI[(MeC=N)(2)CMeNH2]. The X-ray analysis revealed that in the molecule of 2 one I- anion is directly bonded to Nd3+ cation while two other I- anions are not in contact to the metal centre. The molecule of 3 is isostructural to previously obtained Dy and Tm analogues. All three I- anions in it are located away from Nd3+ cation. (C) 2007 Elsevier B.V. All rights reserved.
