title: 4-[2-(3-Methoxyphenyl)ethenyl]-N-methylpyridinium tetraphenylborate.
abstract: In the title compound, C(15)H(16)NO(+).C(24)H(20)B(-), the pyridinium ring of the cation makes a dihedral angle of 4.3 (2) degrees with the benzene ring. Each is rotated in the same direction with respect to the central C-CH=CH-C linkage, by 10.0 (2) and 7.8 (2) degrees , respectively. The anions have a slightly distorted tetrahedral geometry. The most interesting feature of the structure is that the anions form a honeycomb-like hexagonal structure down the b axis through C-H...pi interactions. The hexagon is constructed from six BPh(4)(-) anions. The cations interact in a head-to-tail fashion along [010], forming chains, and pack antiparallel inside the above honeycomb-like structure through C-H...pi interactions.
