The asymmetric unit of the title compound, C8H6N8·2H2O, contains one half-molecule, with the benzene ring on a centre of symmetry, and two uncoordinated water molecules. The benzene ring is oriented at a dihedral angle of 34.43 (12)° with respect to the tetrazole ring. Strong O—H...N hydrogen bonds link the water molecules to the N atoms of the tetrazole ring. In the crystal structure, strong intermolecular O—H...O and O—H...N hydrogen bonds link the molecules into a network. One of the water H atoms is disordered over two positions and was refined with occupancies of 0.50.

In the title compound, C19H15N4+·Br−·C2H5OH, the tetrazole ring makes dihedral angles of 57.44 (9), 50.92 (9) and 4.65 (8)° with the attached phenyl rings. In the crystal, the cation and the anion are linked to each other by intermolecular C—H...Br hydrogen bonds into an infinite chain along thebaxis. The anion and the ethanol solvent molecule are linked by an O—H...Br hydrogen bond. The crystal studied was an inversion twin with a refined component ratio of 0.632 (5):0.368 (5).
