In the title salt, C(19)H(15)N(4) (+)·C(24)H(20)B(-), the tetra-phenyl-borate anion is in a tetra-hedral geometry around the B atom [C-B-C angles of 107.10 (9)-111.79 (9)°]. In the cation, the tetra-zole ring makes dihedral angles of 3.04 (7), 51.75 (7) and 51.13 (7)° with the attached phenyl rings. In the crystal, C-H⋯π inter-actions link the cations and anions into ion pairs.
