三种新型锌配位聚合物 (NH4)n[Zn(Hida)Cl2]n (1)、[Zn(ida)(H2O)2]n (2)、[Zn(Hida)2]n·4nH2O (3) (H2ida = 亚氨基二乙酸) 和单体配合物 [Zn(ida)(phen)(H2O)]·2H2O (4) (phen=1,10-菲咯啉) 已被合成和表征： X射线衍射方法。 1 和 2 形成一维 (1-D) 链结构，而 3 则呈现出具有开放通道的三维 (3-D) 类金刚石骨架。单核配合物4通过氢键和π-π堆积延伸成3-D超分子结构。有趣的是，观察到环状非平面四聚水簇封装在4的三维晶格中。根据1H和13C NMR观察，配合物2在溶液中存在明显的配位，而1和3分解成游离的亚氨基二乙酸配体。单体[Zn(ida)(H2O)3] (5) 被认为是2 中可能的离散物质。这些配位聚合物可以作为氧化锌的良好分子前体。
Three novel zinc coordination polymers (NH4)n[Zn(Hida)Cl2]n (1), [Zn(ida)(H2O)2]n (2), [Zn(Hida)2]n·4nH2O (3) (H2ida = iminodiacetic acid) and a monomeric complex [Zn(ida)(phen)(H2O)]·2H2O (4) (phen=1,10-phenanthroline) have been synthesized and characterized by X-ray diffraction methods. 1 and 2 form one-dimensional (1-D) chain structures, whereas 3 exhibits a three-dimensional (3-D) diamondoid framework with an open channel. The mononuclear complex 4 is extended into a 3-D supramolecular architecture through hydrogen bonds and π-π stacking. Interestingly, cyclic nonplanar tetrameric water clusters are observed that encapsulated in the 3-D lattice of 4. Based on 1H and 13C NMR observations, there is obvious coordination of complex 2 in solution, while 1 and 3 decompose into free iminodiacetate ligand. Monomer [Zn(ida)(H2O)3] (5) is considered as a possible discrete species from 2. These coordination polymers can serve as good molecular precursors for zinc oxide.
