摘要：
Two cerium(IV) complexes of Ce(OQ)(4) (1) (HOQ = 8-hydroxyquinoline) and Ce(L)(2)center dot DME (2 center dot DME) (LH2 = Me2NCH2CH2CH2N{CH2-(3,5-Bu-t(2)-C6H2-2-OH)}(2)) have been synthesized and characterized by elemental analysis, infrared spectra and X-ray crystallography. Complex 1 is a new type of homoleptic 8-quinolinolate lanthanide complex and its overall geometry is like a four-wing-waterwheel. Complex 2 has two tridentate (ONO) amine bis(phenolate) ligands with their terminal N atoms in side-arms without participating in coordination. Both of 1 and 2 can catalyze the oxidation of benzyl alcohol. The conversion of benzyl alcohol by 2 is higher than that by 1 under comparable conditions. (C) 2012 Elsevier B. V. All rights reserved.
