title: 4-[(2'-Cyano-biphen-yl-4-yl)meth-yl]morpholin-4-ium tetra-fluoridoborate.
abstract: In the crystal structure of the title compound, C(18)H(19)N(2)O(+)·BF(4) (-), bifurcated N-H⋯(F,F) hydrogen bonds link the protonated 4'-morpholine-methyl-biphenyl-2-carbonitrile cations and slightly distorted tetra-fluoro-borate anions. π-π inter-actions [centroid-centroid distance = 3.805 (3) Å] help to consolidate the packing. The dihedral angle between the benzene rings in the cation is 57.24 (11)°.
