Neutron diffraction study of a very short O–H⋯N hydrogen bond: crystalline adduct of 2-methylpyridine and pentachlorophenol
Abstract
In the neutron diffraction study of the 1∶1 adduct 2-methylpyridine–pentachlorophenol, a very short O–H⋯N hydrogen bond is found with a sharply defined proton position, and distances of O–H = 1.068(7), H⋯N = 1.535(7) and O⋯N = 2.588(3) Å; the bond order of H⋯N is about 0.24 valence units.
