摘要: 由2-硝基-1,4-对苯二甲酸和4,4'-联吡啶作为起始原料合成了4个金属银的配位聚合物,{[Ag(4,4'-bipy)]·2-Hnbdc·2H₂O·CH₃OH}_n (1),{[Ag(4,4'-bipy)(2-Hnbdc)]}_n (2),{[Ag₂(4,4'-bipy)₂(2-nbdc)]·2H₂O}_n (3),和{[Ag₂(4,4'-bipy)₂(2-nbdc)(H₂O)]·2H₂O}_n (4)。通过IR、元素分析、TG、UV和荧光光谱以及粉末衍射等手段,对配合物进行了表征和性质研究。单晶衍射分析显示,配合物1为1D阴-阳离子型聚合物,配合物2为1D双链结构,且结构中不存在溶剂分子。配合物3和4均为1D链状结构。结构的多样性主要是由配体构象、硝基对苯二甲酸的配位模式以及弱作用(如π-π堆积、Ag…Ag作用以及氢键等)导致的。结构的不同也使得它们的稳定性、紫外吸收以及荧光光谱存在着差异。

Abstract: Four diverse silver coordination polymers with the same components of silver, 4,4'-bipyridine(4,4'-bipy), and 2-nitro-1,4-benzenedicarboxylic acid (2-H₂nbdc) have been synthesized, namely {[Ag(4,4'-bipy)]·2-Hnbdc·2H₂O·CH₃OH}_n (1), {[Ag(4,4'-bipy)(2-Hnbdc)]}_n (2), {[Ag₂(4,4'-bipy)₂(2-nbdc)]·2H₂O}_n (3), and {[Ag₂(4,4'-bipy)₂(2-nbdc)(H₂O)]·2H₂O}_n (4), and characterized by IR, elemental analysis, TG, UV, fluorescence spectra, and powder X-ray analysis. The single crystal X-ray analysis showed that complex 1 is a 1D cation-anionic polymer, complex 2 is a 1D double chain without any solvent, and complexes 3 and 4 are 1D chain structures. Diverse structures differ with respect to molecular conformation, coordination modes of 2-Hnbdc, and weak interactions. In these complexes there are weak bonds, π-π aromatic stacking interactions, Ag…Ag interaction, and hydrogen bonding. The diverse structures are related to the thermal stability, UV absorptions, and fluorescence emissions. CCDC: 945166, 1; 945167, 2; 945168, 3; 945169, 4.
