Smith, Graham & Wermuth, Urs D. (2013) 4-(4-Nitrobenzyl)pyridinium 3-carboxy-4-hydroxybenzenesulfonate. Acta Crystallographica Section E : Structure Reports Online, E69, o206-o206.
In the title salt, C12H11N2O2+·C7H5O6S-, the dihedral angle between the benzene and pyridine rings in the 4-(4-nitrobenzyl)pyridinium cation is 82.7 (2)°. Within the anion there is an intramolecular hydroxy-O-HO(carboxylic acid) bond. In the crystal, the cation forms a single N+-HOsulfonate hydrogen bond with the anion. These cation-anion pairs interact through duplex anion carboxylic acid O-HOsulfonate hydrogen bonds, giving a centrosymmetric cyclic association [graph set R22(16)]. The crystals studied were non-merohedrally twinned.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
