The title novel two-dimensional coordination polymer, {[Zn(2)(C(10)H(8)N(3)O(2))(4)].H(2)O}(n), features a {Zn(2)L(2)} bimetallic ring repeat unit {L is the 3-[(1H-1,2,4-triazol-1-yl)methyl]benzoate ligand}. Each Zn(II) cation of the bimetallic ring is further bonded to two other L ligands, resulting in a novel infinite two-dimensional network structure with two channels of different sizes. The crystallographically unique Zn(II) atom is thus six-coordinated in a distorted octahedral environment of four carboxylate O atoms and two triazole N atoms. Two of these networks interpenetrate in an orthogonal arrangement to form the full three-dimensional framework, with disordered water molecules located in the channels.
标题化合物新型二维配位聚合物{[Zn₂(C₁₀H₈N₃O₂)₄]·H₂O}ₙ具有{Zn₂L₂}双金属环重复单元{L为3-[(1H-1,2,4-三唑-1-基)甲基]苯甲酸酯配体}。双金属环中的每个Zn(II)阳离子进一步与另外两个L配体键合，形成具有两种不同尺寸通道的新型无限二维网络结构。晶体学上独特的Zn(II)原子在由四个羧酸根O原子和两个三唑N原子构成的扭曲八面体环境中呈六配位。其中两个网络以正交排列方式相互贯穿形成完整的三维骨架，通道中存在无序水分子。
