4-{(E)-2-[4-(Diethyl-amino)-phen-yl]ethen-yl}-1-methyl-pyridin-1-ium tetra-phenyl-borate
Abstract:
In the cation of the title salt, C(18)H(23)N(2) (+)·C(24)H(20)B(-), the pyridine ring forms a dihedral angle of 14.23 (6)° with the benzene ring. One of the ethyl groups of the cation was refined as disordered over two sets of sites with equal occupancies.
