  Synthesis and crystal structures of cerium(IV) complexes with 8-quinolinolate and amine bis(phenolate) ligands

  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.

  We prepared alkoxide-bridged heterometallic clusters of cerium and copper by the complexation of two metal alkoxides: treatment of Ce(OtBu)4 with [Cu(OtBu)]4 in a 1:1 metal ratio produced an alkoxide-bridged tetranuclear cluster, Ce2Cu2(OtBu)10 (1). Upon adding 4-substituted pyridine derivatives to complex 1, trinuclear clusters, Ce2Cu(OtBu)9(L) (2a: L = DMAP (4-dimethylaminopyridine); 2b: L = BPY

  我们通过两种金属醇盐的络合制备了铈和铜的醇盐桥联的杂金属簇：用金属比为1：1的[Cu（O t Bu）] 4处理Ce（O t Bu）4产生了醇盐桥联的四核簇，Ce 2 Cu 2（O t Bu）10（1）。向配合物1中添加4-取代的吡啶衍生物后，三核簇团Ce 2 Cu（O t Bu）9（L）（2a：L = DMAP（4-二甲基氨基吡啶）; 2b：L ＝ BPY（4，4′-联吡啶），伴随着0.25当量的[Cu（O t Bu）] 4的释放而获得，其中涉及三配位的铜中心。相反，1与4当量的2,6-二甲基苯基异氰化物（XylNC）和0.5当量的[Cu（O t Bu）] 4反应导致选择性形成CeCu 2（O t Bu）6（CNXyl）2（3）。另外，通过消盐，将Ce 2 K（O t Bu）9与CuCl 2络合，得到Ce 2 CuCl（O t Bu）。图9（4）包括五个坐标的铜中心。这些配合物1 - 4由
