Abstract
The overall molecular geometry of the title compound, C 11 H 12 N 4 O 3 S, is bent, with a dihedral angle of 89.24 (5)° between the best planes through the two aromatic rings. Each molecule behaves as a hydrogen-bond donor toward three different molecules, through its amidic and the two aminic H atoms, and it behaves as a hydrogen-bond acceptor from two other molecules via one of its sulfonamidic O atoms. In the crystal, molecules linked by N - H⋯N and N - H⋯O hydrogen bonds form kinked layers parallel to (001), adjacent layers being connected by van der Waals interactions.
