Abstract

In the cation of the title mol­ecular salt, C15H18NO+·Br, the pyridinium and phenyl rings are inclined to one another by 11.80 (8)°. In the crystal, the Branion is linked to the cation by a C—H...Br hydrogen bond. The cations stack along the b-axis direction and are linked by further C—H...Br inter­actions, and offset π–π interactions [inter­centroid distances = 3.5733 (19) and 3.8457 (19) Å], forming slabs parallel to the ab plane. The effects of the C—H...X inter­action on the NMR signals of the ortho- and meta-pyridinium protons in a series of related ionic liquids, viz. 4-methyl-1-(4-phen­oxy­but­yl)pyridin-1-ium salts, are reported and discussed.
