In the cation of the title compound, C(15)H(16)NO(+).C(24)H(20)B(-), the pyridyl ring makes a dihedral angle of 14.03 degrees with the phenyl ring. The anion has a slightly distorted tetrahedral geometry and forms honeycomb-like sheets which extend along the b axis, forming channels containing the cations. A comparison of packing energies reveals a difference between the title compound and a similar material which has non-linear optical properties.
