Abstract: The cation of the title compound, C₁₄H₁₃NCl⁺·B(C₆H₅)₄^-, has a cis configuration at the C=C double bond. The pyridyl ring makes a dihedral angle of 53.8 (4)° with the benzene ring. Each cation is paired with another related by a twofold rotation through a - interaction and the cations also interact through a weak C-HCl interaction. The crystal structure is further stabilized by C-H interactions.
