Abstract

4,4'-Bipyrazolium [or 4-(1H-pyrazol-4-yl)pyrazolium] bromide monohydrate, C6H7N4+.Br-.H2O, and 4,4'-bipyrazolium perchlorate monohydrate, C6H7N4+.ClO4-.H2O, have closely related layered structures involving tight stacks of antiparallel N-H...N hydrogen-bonded polar bipyrazolium chains [N...N = 2.712 (3) and 2.742 (2) A], which are crosslinked by hydrogen bonds with water molecules and counter-anions.
