四种新型锌(II)金属有机骨架，{[Zn7(trz)6(1,3-bdc)4(H2O)2]·2H2O}n (1)、{[Zn7(trz)6(hip)4(H2O)2]·8H2O}n (2)、[Zn4(trz)4(Hnip)2(nip)]n (3)和[Zn5(trz)2(Hbtc)4(H2O)4]n (4) (Htrz = 1,2,4-三唑，1,3-H2bdc = 1,3-苯二甲酸，H2hip = 5-羟基间苯二甲酸，H2nip = 5-硝基间苯二甲酸，H3btc = 1,3,5-苯三甲酸)，通过以下反应水热合成Zn盐和Htrz分别与四种不同的芳香酸。它们的结构通过单晶X射线衍射分析确定，并通过X射线粉末衍射、元素分析、红外光谱和热重分析进一步表征。化合物 1 和 2 的结构是同构的，其 3D 结构包含由 2D 层 {[Zn7(trz)6]8+}n 与 1,3-bdc (1) 或 hip (2) 互连形成的多维交叉环通道。化合物 3 由 {[Zn4(trz)4]4+}n 层组成，具有 (4, 82) 拓扑结构，按 −ABAB− 堆叠顺序排列，其结构如下：
Four novel zinc(II) metal-organic frameworks, {[Zn7(trz)6(1,3-bdc)4(H2O)2]·2H2O}n (1), {[Zn7(trz)6(hip)4(H2O)2]·8H2O}n (2), [Zn4(trz)4(Hnip)2(nip)]n (3), and [Zn5(trz)2(Hbtc)4(H2O)4]n (4) (Htrz = 1,2,4-triazole, 1,3-H2bdc = 1,3-benzenedicarboxylic acid, H2hip = 5-hydroxyisophthalic acid, H2nip = 5-nitroisophthalic acid, and H3btc = 1,3,5-benzenetricarboxylic acid), have been hydrothermally synthesized by reaction of Zn salt and Htrz with four different aromatic acids, respectively. Their structures were determined by single-crystal X-ray diffraction analyses and further characterized by X-ray powder diffraction, elemental analyses, IR spectra, and TG analyses. The structures of compounds 1 and 2 are isostructural and feature the 3D structure containing multidimensional intersecting ring channels formed by the interconnection of 2D layers {[Zn7(trz)6]8+}n with 1,3-bdc (1) or hip (2). Compound 3 consists of {[Zn4(trz)4]4+}n layers with (4, 82) topology arranged in the −ABAB− stacking sequence, which are con...
