| Zinc(Ⅱ) Coordination Polymers Based on Aromatic Tetracarboxylate: Syntheses, Structures, and Properties | |
| 摘要: 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PtS-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. | |

| Abstract: 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 3Dframework 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 2Dlayers, which are interconnected by weak C-H…Ointeractions to lead to 3Dsupramolecular framework. The thermal stability, and fluorescent emission of the two complexes have also been discussed. CCDC:1018691, 1; 1018790, 2. | |
