title: 2,3-Diphenyl-quinoxalin-1-ium chloride.
abstract: The title compound, C(20)H(15)N(2) (+)·Cl(-), was prepared by the reaction of benzil with o-phenyl-enediamine in refluxing ethanol and then crystallized in 5% hydro-chloric acid. The two phenyl rings are oriented at dihedral angles of 50.93 (8) and 50.28 (8)° with respect to the quinoxalin-1-ium ring system. The dihedral angle between the two phenyl rings is 56.71 (10)°. In the crystal, the cations and anions are linked by N-H⋯Cl and C-H⋯Cl inter-actions, forming chains along the b axis.
