The pyridine—bromine trifluoride (1/1) complex was synthesized and characterized. It crystallizes in the monoclinic space group C2/c with a = 6.9044(9), b = 14.769(2), c = 6.9665(9) Å, β = 111.686(9)°, V = 660.12(16) Å3, Z = 4 at 100 K. The crystal structure consists of isolated non-planar molecules linked via C–H⋯F hydrogen bonds. The obtained results were confirmed by quantum chemical calculations, vibrational and NMR spectroscopy. Calculations of an isolated molecule in the gas phase showed that a planar conformation of the molecule with intramolecular C–H⋯F hydrogen bonds is stable.
