基于联苯四羧酸的Zn(Ⅱ)配合物的合成、结构和性质（英文）

Zinc( Ⅱ) Coordination Polymers Based on Aromatic Tetracarboxylate: Syntheses,Structures, and Properties

利用联苯四羧酸(H4bptc)和双三唑乙烷(bte)合成了2个配位聚合物{[Zn2(bptc)(DMF)2(H2O)]·DMF·H2O}n(1)和{[Zn(bte)(bptc)0.5]·DMF·0.5H2O}n(2)。化合物1为三维Pt S-拓扑结构,在该配合物中每个双核次级构筑单元(SBU){Zn2(O2CR)4}与4个联苯四酸配体相连,从而将配合物构筑成了三维MOF结构。化合物2为二维梯形结构,并通过弱氢键O…H-C将二维层连接为三维结构。同时对配合物的热稳定性和荧光特征进行了讨论。

Two coordination compounds, namely {[Zn2（bptc） （DMF）2（H2O）] · DMF- H2O}n（1） and （[Zn （bte） （bptc）0.5] ·DMF·0.5H2O}n （2） （bte=bis （1,2,4-triazol-1-yl）ethane, H4bptc=biphenyl-3,3＇,5,5＇-tetracarboxylic acid）, have been synthesized and structurally characterized. 1 features a 3D framework with PtS-type topology, in which each binuclear second-building-unit （SBU）{Zn2（O2CR）4} is linked to four biphenyl connectors （and vice versa）. 2 is 2D layers, which are interconnected by weak C-H… O interactions to lead to 3D supramolecular framework. The thermal stability, and fluorescent emission of the two complexes have also been discussed.
