C. R. Girija and N. S. Begum

Abstract: The title compound, C₁₄H₂₁N₂O⁺·ClO₄^-, is an organic non-linear optical material. It crystallizes in the monoclinic space group P2₁ and exhibits second-harmonic generation equivalent to that of urea. The structural study shows extensive electron delocalization in the vinamidinium moiety. The dihedral angle between the vinamidinium moiety and the benzene ring is 81.6  (1)°.
