    The X-ray structures of a series of copper(II) complexes with tetradentate Schiff base ligands derived from salicylaldehyde and polymethylenediamines of varying chain length
    摘要:
    The structures of six N,N'-polymethylene-bis(salicylaldiminato)copper(II) Schiff base complexes with alkyl backbones ranging from two to eight carbons have been determined by X-ray crystallography. The complexes are monomeric when the alkyl chain length is relatively short (two, three, and four CH2 groups) but are dimers when the chain length becomes longer (five, six, and eight CH2 groups). There is a regular increase in the distortion about the copper center as the alkyl chain length approaches four and five carbons, followed by a decrease as the chains become longer. Previously noted trends in electronic spectral, magnetic susceptibility, and microwave dielectric loss data can be accounted for based on this structural information. (C) 2003 Elsevier Science Ltd.

    烷基极化效应和取代基的配位竞争效应对Salen型席夫碱NMR谱的影响
    摘要:
    Salen型席夫碱是一类重要的化合物,应用广泛。为了探索烷基和连接到芳环上的取代基对化学位移的影响,合成了 63 种标题化合物。获得了它们的 1 H NMR 和 13 C NMR 谱图;并研究了烷基链长和取代基对化学位移(δH(CH=N)、δC(CH=N)、δH(OH)和δC(C-OH))的影响。结果表明:(1)烷基极化效应指数(PEI)对上述四个原子的化学位移有重要影响,随着PEI的增加,δH(CH=N)和δc(CH= N)减少,而δH(OH)和δC(C-OH)的值增加。(2)芳环上的取代基X对化学位移的影响与其位置有关,取OH或CH=N为参考。至于取代基对化学位移的影响,哈米特常数σ(X)-OH和激发态取代基参数σ CC ex X - OH以OH为参考的影响与σ(X)-CH= N 和 σ CC ex X - CH = N 以 CH=N 为参照,存在取代基的“同源竞争效应”。(3) X与

    由 N 供体配体组成的 Fe(II) 配合物作为自旋交叉 (SCO) 材料被广泛研究。这是因为 Fe(II) (3d) 的价电子构型可以通过外部刺激(如温度、压力和光照射)在低自旋 (LS, t2g) 和高自旋 (HS, t2geg) 状态之间可逆地切换。最近,Fe(II) 配合物作为染料敏化太阳能电池 (DSSC) 中潜在的光敏剂而备受关注,以取代更昂贵和有毒的 Ru(II) 配合物。出于这些目的,源自席夫碱的配体非常适合,因为它们易于制备、结构通用且与大多数过渡金属离子形成稳定的配合物。本文介绍了三种结构不同的希夫碱 L1、H2L2 和 H2L3(图 1)以及相应的 Fe(II) 配合物的合成。配体 L1 是中性 N3 供体希夫碱,H2L2 是多 N 供体共轭希夫碱,H2L3 具有两个由八碳脂肪链隔开的 N,O 供体。主要目的是显示配体的不同供体原子对形成的 Fe(II) 配合物的结构

Copper(II) complexes of H2L1, H2L2 and H2L4 were dimeric, while that of H2L3 was dinuclear with chelating CH3COO ligand.
