Abstract

Two novel three-dimensional Zn-MOFs (zinc metal-organic frameworks), Zn(5)(μ(3)-OH)(BTC)(3)(Phen)(4)·5H(2)O (denoted as HUT-11) and Zn(4)(μ(4)-O)(BTC)(2)(Phen)(2)·4H(2)O (denoted as HUT-12), have been synthesized by metal-ligand-directed assembly under hydrothermal conditions. Here, BTC and Phen are denoted as 1,3,5-benzenetricarboxylate and phenanthroline. HUT-11 contains two kinds of secondary building units (SBUs), Zn(3)(μ(3)-OH)(COO)(5) clusters and Zn(2)(COO)(4) clusters. This material exhibits a new three-dimensional (3,4,5)-connected topology with the Schläfli symbol (4·6·8)(2)(4·8(2))(4·6(4)·8(5))(4(2)·6(2)·8(2)). Two perpendicular planes cross at five coordinated Zn1-Zn3-Zn5 nodes, giving a new three-dimensional network. HUT-12 is composed of Zn(4)(μ(4)-O)(COO)(6) clusters as the secondary building units and displays a two-dimensional (3,6)-connected TiS(2) related net topology with the Schläfli symbol (4(2)·6)(4(4)·6(2)·8(8)·10). Both MOFs show blue light emission and a high thermal stability above 673 K.

两种新型zn - mof:结构与表征。

采用金属配体定向组装方法，在水热条件下合成了Zn(5)(μ(3)-OH)(BTC)(3)(Phen)(4)·5H(2)O (HUT-12)和Zn(4)(μ(4)-O)(BTC)(2)(Phen)(2)·4H(2)O (HUT-12)两种新型三维锌金属有机骨架。其中，BTC和Phen分别表示为1,3,5-苯三羧酸盐和菲罗啉。HUT-11包含两种次级结构单元(SBUs): Zn(3)(μ(3)-OH)(COO)(5)簇和Zn(2)(COO)(4)簇。该材料呈现出一种新的三维(3,4,5)连接拓扑结构，其符号为Schläfli(4·6·8)(2)(4·8(2))(4·6(4)·8(5))(4(2)·6(2)·8(2))。两个垂直平面在五个协调的Zn1-Zn3-Zn5节点相交，形成一个新的三维网络。HUT-12以Zn(4)(μ(4)-O)(COO)(6)簇为次级结构单元，呈现二维(3,6)连接的ti(2)相关网络拓扑结构，符号为Schläfli(4(2)·6)(4(4)·6(2)·8(8)·10)。这两种mof在673 K以上均表现出蓝光发射和较高的热稳定性。

期刊介绍： Acta Crystallographica Section B: Structural Science, Crystal Engineering and Materials publishes scientific articles related to the structural science of compounds and materials in the widest sense. Knowledge of the arrangements of atoms, including their temporal variations and dependencies on temperature and pressure, is often the key to understanding physical and chemical phenomena and is crucial for the design of new materials and supramolecular devices. Acta Crystallographica B is the forum for the publication of such contributions. Scientific developments based on experimental studies as well as those based on theoretical approaches, including crystal-structure prediction, structure-property relations and the use of databases of crystal structures, are published.
