Guanidinium 2-carboxy-6-nitrobenzoate monohydrate: A two-dimensional hydrogen-bonded network structure
Smith, Graham, Wermuth, Urs D., & White, Jonathan M. (2007) Guanidinium 2-carboxy-6-nitrobenzoate monohydrate: A two-dimensional hydrogen-bonded network structure. Acta Crystallographica. Section E: Structure Reports Online, E63(8), o3527-o3528.
In the structure of the title compound, CH6N3+ . C8H4NO6- . H2O, obtained from the reaction of guanidine carbonate with 3-nitrophthalic acid, the 2-carboxylic acid group is deprotonated and participates in an asymmetric cyclic R2/1(6) hydrogen-bonding associatiuon with the guanidine cation together with a bridging water molecule of solvation. A conjoint R2/1(7) facial association involving a nitro O-atom acceptor together with a further five guanidinium N-H...O hydrogen bonds, as well as a strong carboxyl-water interaction [2.528(3) Ang.], give a two-dimensiional network structure.
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.
