摘要：

Polymorph VI of 4-amino-N-(2-pyridyl)benzenesulfonamide, C11H11N3O2S, is monoclinic (space group P2(1)/n). The asymmetric unit contains two different tautomeric forms. The structure displays N-H center dot center dot center dot N and N-H center dot center dot center dot 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.
