3-carbamoyl-1-(10-carboxydecyl)pyridin-1-ium salts with four anions (PF6− (1), BF4− (2), NO3− (3), and Br− (4)) have been synthesized and characterized by single-crystal X-ray diffraction. All four salts have a primary L-shaped cation conformation, and each pair of cations forms a similar well-defined rectangular motif of nicotinamide cations and fattyacid groups via N–H⋯O or C–H⋯O hydrogen bonding
