The crystal structures of the 1:1 proton-transfer compounds of 5-sulfosalicylic acid with the ortho-substituted monocyclic heteroaromatic Lewis bases, 2-aminopyridine, 2- hydroxypyridine and 2-aminopyrimidine, viz. 2-aminopyridinium 5-sulfosalicylate (1), 2-hydroxypyridinium 5-sulfosalicylate monohydrate (2) and 2-aminopyrimidinium 5- sulfosalicylatemonohydrate (3) have been determined and their hydrogen-bonding patterns described. All compounds are monoclinic, space group P21/c, with Z=4 in cells with dimensions a=7.898(5), b=11.159(11), c=14.912(7) A° , β =96.849(11)◦ (1);=7.260(2), b=15.292(3), c=12.615(2) A° , β =102.45(5)◦ (2) and a=7.0430(7), b=12.1871(16), c=16.2825(12) A° , β =101.364(7)◦ (3). All three compounds show some molecular disorder, in 1 within the cation species and with both 2 and 3, a similar rotational disorder in the anion sulfonate group. Hydrogen bonding in all three compounds together with significant cation-anion or cation-cation inter-ring π–π interactions generate three-dimensional layered polymer structures.

Search Google Scholar™

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.
