Abstract

A novel Zn^II coordination polymer, namely, poly[{μ₂-bis[4-(2-methyl-1H-imidazol-1-yl)phenyl]methanone-κ²N³:N^3'}(μ₂-5-bromobenzene-1,3-dicarboxylato-κ²O¹:O³)zinc(II)], [Zn(C₈H₃BrO₄)(C₂₁H₁₈N₄O)]_n or [Zn(Br-BDC)(MIPMO)]_n, (I), has been synthesized by the solvothermal method using 5-bromoisophthalic acid (Br-H₂BDC), bis[4-(2-methyl-1H-imidazol-1-yl)phenyl]methanone (MIPMO) and Zn(NO₃)₂·6H₂O. Structure analysis showed that compound (I) displays twofold parallel interwoven sql nets. Fluorescence experiments confirmed that the compound can sensitively and selectively detect nitrofurantoin (NFT) in aqueous medium. In addition, the possible fluorescence quenching mechanisms of compound (I) toward NFT are investigated.

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.
