Abstract

The crystal structure of the anhydrous 1:1 proton-transfer compound of 5-sulfosalicylic acid (3-carboxy-4-hydroxybenzenesulfonic acid) with 3-aminobenzoic acid, C7H8NO2+·C7H5O6S-, shows heteromeric cyclic R22(8) carboxylic acid dimers formed through hydrogen-bonding interactions between the cation and anion species. Aminium-sulfonate N-HO interactions link these dimers into zigzag chains and also give interchain associations. Cation-anion - ring interactions are also present, resulting in a three-dimensional layered polymer structure.

Citation counts are sourced monthly from Scopus and Web of Science® 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.
