The mixture ZnF2/HFaq./Hamtetraz (Hamtetraz = 5-aminotetrazole) with the molar ratio 10/80/10 reacts at 160 °C in different solvents (methanol/water and water respectively) to give two new 3D compounds: (Zn4F4(amtetraz)4)∙H2O (1) and (Zn4F4(H2O)(amtetraz)4)·H2O (2). The structures, determined by single crystal X-ray diffraction, exhibit neutral 3D-frameworks with narrow cavities that contain water molecules. Each network is built up from two types of parallel chains connected by aminotetrazolate ligands. The comparison of 1 and 2 with literature compounds shows that the nature of the polar solvent, aprotic or protic, influences the network characteristics, as well as the condensation of inorganic species or the bridging mode of the organic moieties. The luminescence properties of the zinc fluoro-aminotetrazolates are discussed.

溶剂对杂化氟化物3D拓扑的影响:Zn(II)配位化合物的合成,结构和发光性质

混合物ZnF 2 / HF水溶液。 摩尔比为10/80/10的/ H amtetraz(H amtetraz = 5-aminotetrazole)在160°C下于不同溶剂(分别为甲醇/水和水)中反应生成两种新的3D化合物:(Zn 4 F 4amtetraz4)∙H 2 O(1)和(Zn 4 F 4(H 2 O)(amtetraz4)·H 2O(2)。通过单晶X射线衍射确定的结构表现出具有狭窄空腔的中性3D框架,该空腔包含水分子。每个网络均由通过氨基四唑酸酯配体连接的两种类型的平行链构成。1和2与文献化合物的比较表明,非质子或质子性极性溶剂的性质会影响网络特性,以及无机物质的缩合或有机部分的桥接方式。讨论了氟代氨基四唑酸锌的发光性质。
