Abstract
In the title salt, C19H15N4+center dot C24H20B-, the tetraphenylborate anion is in a tetrahedral geometry around the B atom [C-BC angles of 107.10 (9)-111.79 (9)degrees]. In the cation, the tetrazole ring makes dihedral angles of 3.04 (7), 51.75 (7) and 51.13 (7)degrees with the attached phenyl rings. In the crystal, C-H center dot center dot center dot interactions link the cations and anions into ion pairs.
