5-Di­methyl­amino-N,N-di­methyl-3-(4-pyridyl)-2,4-pentadieniminium tetra­fluoro­borate

The crystal structure of the title salt, C14H20N3+·BF4−, shows that the pentamethinecyanine moiety of the cation is essentially planar and adopts an all-trans conformation. The plane of the pyridyl substituent makes a dihedral angle of 60.58 (9)° with the pentamethinecyanine plane.
