    Crystal structures of [M(NTf2)3(H2O)n] (M=Eu and Yb) and a template effect of linear molecules on the 3D hydrogen bonding network structure of [Eu(NTf2)3(H2O)3]
    摘要:
    Lewis acid catalysts [Eu(NTf2)(3)] and [Yb(NTf2)(3)] can be easily crystallized from a p-xylene solution in the presence of carboxylic acids and a small amount of water to give a trihydrate and a pentahydrate, respectively. In the crystallization of [Eu(NTf2)(3)(H2O)(3)], linear molecules such as n-alkanes and n-alkanoic acids act as templates to form crystals belonging to the trigonal space group P (3) over bar with a hexagonal cylindrical structure, which is constructed by 3D hydrogen bonding network. On the other hand, [Eu(NTf2)(3)(H2O)(3)] crystallized in the cubic space group P2(1)3 in the presence of a bulkier carboxylic acid, cyclohexanecarboxylic acid. In both [Eu(NTf2)(3)(H2O)(3)] crystals, NTf2- ligands act as bidentate ligands coordinating to the Eu atom through two oxygen atoms. [Yb(NTf2)(3)] crystallized as a pentahydrate in the monoclinic space group P2(1)/n, in which NTf2- ligands coordinated to the Yb atom with only one oxygen atom. (c) 2006 Elsevier B.V.

    The electrochemical behavior of samarium (Sm), europium (Eu), and ytterbium (Yb) was investigated in the hydrophobic room-temperature molten salts based on bis(trifluoromethylsulfonyl)imide (TFSI - ) combined with either 1-ethyl-3-methylimidazolium (EMI + ) or 1-n-butyl-l-methylpyrrolidinium (BMP + ). The redox reactions of Sm(III)/Sm(II), Eu(III)/Eu(II), and Yb(III)/Yb(II) were observed at -1.6, -0

    coordinating OTf- anion completely replaces the less Lewis basic Tf 2 N- anion in the first coordination sphere of the lanthanide ion. As expected, such a ligand exchange could not be observed for Yb(OTf) 3 in [C 4 mpyr][Tf 2 N]. The ion exchange in the lanthanide coordination sphere can be efficiently monitored by means of cyclic voltammetry (CV). CV measurements also indicate that Yb 3+ adopts a mixed OTf -
