  Synthesis and characterization of square planar and square pyramidal copper(II) compounds with tridentate Schiff bases: Formation of a molecular zipper via H-bonding interaction

  摘要：

  Three copper(II) compounds, [Cu(L-1)(H2O)(2)]NO3 (1), [Cu(L-1)(N-3)]center dot 2H(2)O (2), and [Cu(L-2)Cl-2] (3), where HL1 = 2-[(pyridine-2-ylmethylene)-amino]-phenol and L-2 = (2-methoxy-phenyl)-pyridin-2-ylmethylene-amine are tridentate Schiff-base ligands, have been prepared and characterized by elemental analysis, IR and UV-Vis spectroscopy, Thermo-gravimetric study and single-crystal X-ray diffraction. Compound 1 crystallizes in triclinic space group P (1) over bar with cell dimensions a = 7.725(5), b = 9.140(5), c = 11.162(5), alpha = 102.229(5), beta = 104.330(5) and gamma = 104.710(5), whereas compounds 2 and 3 crystallize in monoclinic space groups P2(1)/c and P2(1)/n respectively with cell dimensions of a = 10.2111(3), b = 6.6366(2), c = 20.8098(5), beta = 101.851(2) (for 2) and a = 7.9914(1), b = 18.2591(3), c = 9.5695(2), beta = 91.384(1) (for 3). In compound 1, copper(II) center exhibits a distorted square pyramidal geometry while in case of compound 2, copper(II) acquires square planar geometry. The geometry of copper(II) in compound 3 is intermediate between square pyramid and a structure, which is known as 'inverse square pyramid'. A zipper like infinite chain was formed in compound 2 via hydrogen bonding network between the complex moiety, azide and enclathrated water molecules. (C) 2012 Elsevier B.V. All rights reserved.

  Abstract A tridentate Schiff base probe L (2-NC5H4)C(H)=N(C6H4OH-2) was synthesized via a facile reaction. Probe L showed weak fluorescence emission that originated from intermolecular proton transfer in solution. With addition of Cu2+, the emission of L was quenched by the paramagnetic nature of Cu2+. However, after the solution of L and Cu2+ was refluxed, the emission presented a completely opposite

  摘要 通过容易的反应合成了三齿席夫碱探针L（2-NC 5 H 4）C（H）＝ N（C 6 H 4 OH-2）。探针L显示弱的荧光发射，这是由于溶液中的分子间质子转移引起的。添加Cu 2+时，L的发射因Cu 2+的顺磁性而被淬灭。然而，在L和Cu 2+的溶液回流后，发射呈现完全相反的结果，从荧光猝灭变为荧光增强。荧光增强归因于Cu 2+络合物的平面顺式结构。因此，改变荧光探针L向Cu的发射行为的策略开发了2+；在甲醇溶液中实现了Cu 2+检测的“开启”模式。简单的回流使探针L可以用作甲醇溶液中Cu 2+的发光荧光传感器，并提高了检测Cu 2+的灵敏度和选择性。将H 2 O添加到Cu 2+络合物溶液中后，荧光增强作用增强，可用于检测甲醇中的水含量。
