Abstract

A new Pb^II coordination polymer, poly[0.75(aqua)[μ₃-4,4'-(1H,1'H-[2,2'-biimidazole]-1,1'-diyl)dibenzoato-κ⁵O,O';N;O'',O''']]lead(II)] 1.25-hydrate], {[Pb(C₂₀H₁₂N₄O₄)(H₂O)_0.75]·1.25H₂O}_n or {[Pb(L)(H₂O)_0.75]·1.25H₂O}_n (1) [H₂L = 4,4'-(1H,1'H-[2,2'-biimidazole]-1,1'-diyl)dibenzoic acid], was synthesized under solvothermal reaction conditions and characterized using microanalysis, IR spectroscopy and thermogravimetric analysis. Single-crystal structure analysis reveals that a two-dimensional corrugated layer structure is formed in 1 and that neighbouring layers are further extended into a three-dimensional structure by hydrogen-bonding interactions. In addition, a fluorescence sensing experiment towards Cu²⁺ based on the polymeric Pb^II complex was carried out.

半刚性双位2,2-双咪唑衍生物构建PbII配位聚合物:合成、晶体结构及表征

在溶剂热反应条件下合成了一种新的PbII配位聚合物，聚[0.75(水)[μ3-4,4'-(1H,1' h -[2,2'-双咪唑]-1,1'-二酰基)二苯甲酸-κ 50,O';N;O'，O']]铅(II)] 1.25-水合物]，{[Pb(C20H12N4O4)(H2O)0.75]·1.25H2O} N或{[Pb(L)(H2O)0.75]·1.25H2O} N (1) [H2L = 4,4'-(1H,1' h -[2,2'-双咪唑]-1,1'-二苯甲酸]，并用微量分析、红外光谱和热重分析对其进行了表征。单晶结构分析表明，在1中形成二维波纹层结构，相邻层通过氢键相互作用进一步扩展成三维结构。此外，还进行了基于聚合物PbII配合物对Cu2+的荧光传感实验。

期刊介绍： Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
