The two compounds contain essentially identical hydrogen-bond networks between the hydraziniumcation and the acid molecules, which define closely comparable two-dimensional layers in the structures. The planes of the aromatic rings within both structures are approximately parallel and the layers are stacked with comparable intermolecular interactions.enArticle
