Abstract

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 the b axis. 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).
