(3R,4S)-3-Methyl-4-phenyl-2-[(R)-1-phenyl-eth-yl]-3,4-di-hydro-isoquinolin-2-ium tetra-fluorido-borate.
The title salt, C24H24N(+)·BF4 (-), is one of two possible dias-tereoisomers having a different configuration of the asymmetric centre in the α-phenyl-ethyl substituent, whose absolute configuration was established to be R. The two phenyl substituents of the cation have a cofacial orientation, albeit with a long centroid-centroid separation of 4.129 (3) Å. The crystal structure exhibits numerous C-H⋯F contacts between counter-ions, with the tetra-fluorido-borate anion surrounded by five iminium cations.
