The crystal structures of the 1:1 proton-transfer compounds of 3,5-dinitrosalicylic acid (dnsa) with a series of common polycyclic aromatic and heteroaromatic anines (quinoline, 1-naphthylamine, 1,2,3,4-tetrahydroquinoline, quinaldic acid, benzamidazole, 1,10-phenanthroline and 2,2'-bipyridine) have been determined and the hydrogen-bonding associations in each analyzed. The compounds are [(C9H8N)+ (dnsa)-] (1), [(C10H10N)+ (dnsa)-] (2), [(C9H12N)+ (dnsa)-] (3), [(C10H8NO2)+ (dnsa)-] (4), [(C7H7N2)+ (dnsa)-] (5), [(C12H9N2)+ (dnsa)-] (6), [(C10H9N2)+ (dnsa)-] (7).In all compounds, protonation of either the substituent amino group or the hetero-N of the Lewis base occurs, with subsequent hydrogen bonding via this and other hydrogen donors variously to the carboxylate, phenate and nitro oxygen acceptors of the dnsa anions. The result is the formation of primary N+-H...O associations which with secondary peripheral interactions, which within this set of compounds includes an increased incidence of aromatic C-H...O associations, give framework polymer structures. In three of the compounds [1,4 and 6], , cation-anion pi-pi interactions are also found. The completion of this series of compounds has now allowed the categorization of the molecular assembly modes in the proton-transfer compounds of 3,5-dinitrosalicylic acid.

Citation countsare sourced monthly fromand 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 downloadsdisplays 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.
