4-Amino-N-(3-methoxypyrazin-2-yl)benzenesulfonamide

Abstract

The overall molecular geometry of the title compound, C11H12N4O3S, 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.
