4-(2,4,6-trinitroanilino)benzoic acid (p-picraminobenzoic acid), C13H8N3O8, obtained by the reaction of 2,4,6-trinitrobenzenesulfonic acid (picrylsulfonic acid) with 4-aminobenzoic acid in 2-propanol-water, forms a two-dimensional hydrogen-bonded network based on centrosymmetric cyclic R2/2(8) carboxylic acid dimers which are extended through lateral N-H...O(carboxyl) interactions. The amino group also makes an intramoleclar N-H...O(nitro) hydrogen bond, while the two aromatic ring systems are, as expected, non-coplanar, the C-C-N-C torsion angles being 152.0(2)(picryl) and 136.1(2)deg. (benzoic acid).
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.
