Abstract

A new "click" ligand, 2,6-bis(1-(pyridin-4-ylmethyl)-1-1,2,3-triazol-4-yl)pyridine () featuring a tridentate 2,6-bis(1,2,3-triazol-4-yl)pyridine (tripy) pocket and two pyridyl (py) units was synthesized in modest yield (42%) using the copper(I) catalyzed azide-alkyne cycloaddition (CuAAC) reaction. The coordination chemistry of the ligand with silver(I) and iron(II) ions was examined using a battery of solution (¹H and DOSY (diffusion ordered spectroscopy) nuclear magnetic resonance (NMR), infrared and absorption spectroscopies, high-resolution electrospray ionization mass spectrometry (HR-ESI-MS)), and solid state (X-ray crystallography, elemental analysis) techniques. When treated with silver(I) ions, the ligand forms discrete [Ag()]⁺ (X, where X = BF₄, NO₃ or SbF₆) complexes in dimethyl sulfoxide (DMSO) solution but these complexes crystallize as coordination polymers. The addition of Fe(H₂O)₆₂ to an acetonitrile solution of the ligand forms the expected monomeric octahedral [Fe()₂] complex and treatment of the iron(II) complex with AgBF₄ generates a heterometallic linear coordination polymer.

摘要

一种新的“点击”配体 2,6-双(1-(吡啶-4-基甲基)-1,2,3-三唑-4-基)吡啶()，具有三齿 2,6-双(1,2,3-三唑-4-基)吡啶(tipy)口袋和两个吡啶基(py)单元，通过铜(I)催化的叠氮-炔环加成(CuAAC)反应以中等产率(42%)合成。使用一系列溶液(¹H 和 DOSY(扩散有序光谱)核磁共振(DOSY NMR)、红外和吸收光谱、高分辨率电喷雾电离质谱(HR-ESI-MS))和固态(X 射线晶体学、元素分析)技术研究了配体与银(I)和铁(II)离子的配位化学。用银(I)离子处理时，配体在二甲基亚砜(DMSO)溶液中形成离散的[Ag()]⁺(X，其中 X = BF₄、NO₃或 SbF₆)配合物，但这些配合物结晶为配位聚合物。向配体的乙腈溶液中加入Fe(H₂O)₆₂生成预期的单核八面体[Fe()₂]配合物，用 AgBF₄处理铁(II)配合物生成杂金属线性配位聚合物。
