  用于超分子配位化学的新型多齿配体：含吡啶基和噻唑基供体单元的配体的双螺旋和三螺旋配位体

  摘要：

  已经制备了四个新的多齿N-供体L 1 -L 4配体，它们包含吡啶基和噻唑基供体单元的组合。基于α-溴乙酰基单元与硫酰胺的反应形成噻唑基环，这些配体的合成是容易且高产率的。的延伸线性序列邻-连接的N-供杂环（4对于L 1，六对于L 2 ;五对于L 3 ;和六个对于L 4）使人想起了众所周知的线性低聚吡啶，尽管这些新的配体更容易制造并且具有显着不同的几何配位性质，因为五元噻唑基环的存在会导致配体主链自然断裂成明显的二齿或七齿域。因此，四齿配体L 1划分为两个双齿结构域，以产生 具有六坐标的第一行过渡金属指示剂（M = Co，Cu，Zn）的双核三螺旋[M 2（L 1）3 ] 4+。六齿配体L 2划分为两个齿状结构域，得到双核双螺旋结构[M 2（L 2）2 ] 4+ 与六配位金属离子（M = Cu，Zn）。在双螺旋[Cu 2（L 3） 2 ] 4+中，五齿配体L 3仅使用其两个末端双齿结合位点，从而导致四配位的Cu（

All complexes were isolated as hexafluorophosphate salts and characterized by IR, NMR, mass spectrometry and UV-vis spectroscopy. The X-ray crystal structure analyses of [3]PF6, [5]PF6, [8](PF6)(2) and [12](PF6)(2) reveal a typical piano-stool geometry around the metal centers with a five-membered metallo-cycle in which 4,4'-bis(2-pyridyl-4-thiazole) acts as a N, N'-chelating ligand.

  Reaction of Cd(ClO4)(2) with the potentially tetra-(L-1), penta-(L-2) and hexadentate (L-3) pyridine-thiazole-containing ligands gives [Cd-2(L-1)(3)(H2O)][ClO4](4) (a dinuclear triple helicate), mononuclear [Cd(L-2)(ClO4)(2)], and [Cd-2(L-3)(2)(ClO4)(CH3CN)][ClO4](3) (a dinuclear double helicate), respectively. In [Cd-2(L-1)(3)(H2O)][ClO4](4) two of the ligands L-1 partition into two bi dentate pyridylthiazole domains whereas the remaining ligand partitions into a bidentate (pyridyl-thiazole) and monodentate (coordinating pyridyl unit with a pendant thiazole) unit; one Cd(II) centre is coordinated by three bidentate ligand fragments, whereas the other is coordinated by two bidentate and one monodentate ligand fragments as well as a water molecule. This low-symmetry arrangement is retained in solution. In [Cd(L-2)(ClO4)(2)], L-2 acts as a planar pentadentate equatorial ligand with perchlorate anions coordinated at the axial sites; the ligand has a shallow helical twist to minimise steric interactions between the terminal pyridyl H-6 protons, which are directed towards each other. In [Cd-2(L-3)(2)(ClO4)(CH3CN)][ClO4](3), the potentially hexadentate ligand L-3 is partitioned into terdentate (pyridyl-thiazole-pyridyl) and bidentate (pyridyl-thiazole) coordination domains with a non-coordinated terminal pyridyl unit; each Cd(II) centre is coordinated by one terdentate and one bidentate ligand fragment, with the sixth site being occupied by MeCN at one Cd(II) site and a perchlorate anion at the other. Again, the low symmetry coordination mode of the ligands is retained in solution although the two metal centres become equivalent. (C) 2003 Elsevier Science Ltd. All rights reserved.
