Polymorph VI of sulfapyridine: interpenetrating two- and three-dimensional hydrogen-bonded nets formed from two tautomeric forms

Polymorph VI of 4‐amino‐N‐(2‐pyridyl)benzenesulfonamide, C11H11N3O2S, is monoclinic (space group P21/n). The asymmetric unit contains two different tautomeric forms. The structure displays N—H...N and N—H...O hydrogen bonding. The two independent molecules form two separate two‐ and three‐dimensiona...

Description
Summary:Polymorph VI of 4‐amino‐N‐(2‐pyridyl)benzenesulfonamide, C11H11N3O2S, is monoclinic (space group P21/n). The asymmetric unit contains two different tautomeric forms. The structure displays N—H...N and N—H...O hydrogen bonding. The two independent molecules form two separate two‐ and three‐dimensional hydrogen‐bonded networks which interpenetrate. The observed patterns of hydrogen bonding are analogous to those in polymorph I of sulfathiazole.
