Abstract

Crystallography Physical Sciences Science & Technology
The six-membered heterocycle in the title compound, C18H16BrN3O4S, adopts a sofa conformation. Intramolecular N-H center dot center dot center dot N and O-H center dot center dot center dot O hydrogen bonds stabilize the molecular conformation by forming a five-and a six-membered ring, respectively. The crystal packing is stabilized by intermolecular C-H center dot center dot center dot O hydrogen bonds.
