    Abstract New vanadyl(IV) complexes of tetradentate Schiff-base dianions containing one, two or three carbon atoms between the two iminato-nitrogen atoms are described. The compounds are either mononuclear or polymeric, as shown by the value of v(V=O), and depending upon the Schiff-base dianion. There is no evidence for electron delocalization along the polymeric chains. Some vanadium(III) complexes
    摘要描述了在两个亚基氮原子之间包含一个,两个或三个碳原子的四齿席夫碱双阴离子新的(IV)配合物。这些化合物是单核的或高分子的,如v(V = O)的值所示,具体取决于席夫碱的二价阴离子。没有证据表明电子会沿着聚合物链发生离域化。还分离了一些双齿席夫碱单阴离子(III)配合物。报道了[VO(2-OC6H4CHNH)2]的晶体结构和[V(Prhap)3]·甲苯[HPrhap = 2-HOC6H4C(Me)NCH2CH2Me]的结构的初步数据。

    Herein we investigate imaginary third order NLO activity, optical limiting capability and first hyperpolarizabilities of five Ni (II) salen complexes using experimental and theoretical methods. The complexes are tuned to have different NLO response by changing mainly the diimine spacer group. Out of the compounds reported, the one with o‐phenylene spacer group exhibits the highest NLO activity comparable
    在本文中,我们使用实验和理论方法研究了五个Ni(II)salen配合物的虚构三阶NLO活性,光学极限能力和第一超极化率。通过主要改变二亚胺间隔基团,将复合物调整为具有不同的NLO响应。在报告的化合物中,带有o的化合物-亚苯基间隔基团表现出最高的NLO活性,可与聚合物和半导体媲美,其次是具有乙烯间隔基单元的化合物。活动顺序是π-离域化程度的直接函数。此外,所有测试的化合物都具有出色的光学限制能力,这使其成为制造此类器件的极佳材料。实验结果通过理论值M06 / 6-31G *的DFT进行的前沿轨道计算得到了证实,并且与芳香族间隔基团形成的络合物具有最小的能隙和最高的活性。还以相同的理论平计算了总偶极矩,极化率和第一超极化率,这也与实验观察到的结果一致。

    In this study, a novel Mn(III)–Schiff base complex was synthesized and characterized. The structure of this complex was determined to be a deformed octahedral coordination sphere by single-crystal X-ray diffraction analysis. The Mn(III)–Schiff base complex was supported on silica-coated iron magnetic nanoparticles via axial coordination by one-step complex anchoring to produce a heterogenized nanocatalyst
    本研究合成并表征了一种新型的 Mn( III )-Schiff 碱配合物。通过单晶X射线衍射分析确定该配合物的结构为变形的八面体配位球。Mn( III )-Schiff碱配合物负载在二氧化硅包覆的磁性纳米颗粒上通过一步复杂锚定的轴向配位产生异质纳米催化剂。之后,通过傅里叶变换红外光谱(FTIR)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、能量色散X射线光谱(EDX)、热重分析(TGA)、振动样品磁力测定法对复合物进行表征(VSM) 和粉末 X 射线衍射 (XRD)。此外,使用原子吸收光谱来确定负载属的量。多相纳米催化剂有效地催化多种硫化物和烯烃与 H 2 O 2的氧化在玻璃碳电极存在下,向反应混合物施加电压。结果表明,与类似化学氧化反应的情况相比,对反应混合物施加电位可以显着缩短反应时间。此外,苯乙烯的电化学氧化获得了优异的周转频率值(17 750 h -1 )。此外,在甲基
  • Complexation of a Schiff base ligand having two coordination sites (N2O2 and O2O2) with lanthanide ions (Ln = La, Pr): an NMR study
    作者:Jean-Pierre Costes、Jean-Pierre Laussac、Franck Nicodème
    DOI:10.1039/b201136k
    日期:2002.6.27
    With the help of spectroscopic data, we have characterized several isolated entities resulting from the reaction of lanthanide ions with a hexadentate Schiff base ligand obtained by reacting o-vanillin and 1,2-diaminoethane. This H2L ligand possesses two coordination sites, an N2O2 inner site and an O2O2 outer site. In the first isolated complex, formulated as (H2L)Pr(NO3)3·H2O 1Pr, the NMR data confirm that the Pr3+ ion is only linked to the ligand by its deprotonated phenol functions while the ligand does exist in a neutral zwitterionic phenolato-iminium form (O−, NH+) in agreement with a migration of the protons from the phenolic functions to the imine groups. Deprotonation of the ligand in 1Pr yields a new and original product, LPr(NO3)·H2O·CH3OH 2Pr for which spectroscopic results agree with a coordination of the Pr3+ ion at the N2O2 site. This result, which is surprising in view of the oxophilic character of the lanthanide ions, is also confirmed by comparison with the NMR data of the LZnPr(NO3)3 complex 3Pr that retains the Pr3+ ion in the O2O2 site. Another anionic complex 4Pr, L2PrCs, with two ligands linked to the lanthanide centre by their N2O2 sites is also isolated. Starting with the mononuclear cationic or anionic entities, 2Pr or 4Pr, we have not been able to isolate and characterize genuine homo- or hetero-dinuclear lanthanide complexes.
    在光谱数据的帮助下,我们对由系离子与通过反应香草醛和1,2-二乙烷获得的六齿式施夫碱配体反应所产生的几种孤立实体进行了表征。该H2L配体具有两个配位位点,一个是N2O2内位点,另一个是O2O2外位点。在第一个孤立的配合物中,命名为(H2L)Pr(NO3)3·H2O 1Pr,NMR数据确认Pr3+离子仅通过去质子化的官能团与配体相连,同时配体确实以中性内盐基-亚胺形式存在(O−, NH+),这与质子从官能团迁移到亚胺基团的现象一致。在1Pr中,配体的去质子化生成了一种新颖的产物 LPr( )· ·CH3OH 2Pr,光谱结果表明Pr3+离子在 位点配位。考虑到系离子的亲氧性,这一结果令我们感到惊讶,同时通过与保留Pr3+离子在O2O2位点的LZnPr( )3复合物3Pr的NMR数据进行比较也得到了验证。另一个阴离子复合物4Pr,L2PrCs,具有两个配体通过其 位点与系中心相连也被孤立。从单核阳离子或阴离子实体2Pr或4Pr出发,我们未能孤立和表征真正的同种或异种双核系配合物。
