H 5 ), (2,3,5,6-Me 4 C 6 H)CH 2 (2′-Me + NC 5 H 4 ), (2,3,4,5,6-Me 5 C 6 )CH 2 ( + NC 5 H 5 ) and (2,3,4,5,6-Me 5 C 6 )CH 2 (2′-Me + NC 5 H 4 ). The data are analysed in terms of the preferred conformations adopted by such cations in formations, where both aryl and pyridinium rings are twisted in the same direction with respect to the C ar -CH 2 -N ar reference plane. In contrast, tri-ortho-substituted
