Abstract: The crystal structure of 2,6-lutidine (2,6-dimethylpyridine, C7H9N), has been determined at 120 (2) K following in situ crystal growth from the liquid. In the non-centrosymmetric space group Fdd2, the asymmetric unit comprises half a molecule, each molecule being sited on a crystallographic diad axis. Molecules are linked via linear C-HN interactions into one-dimensional chains that align in a parallel manner, giving rise to macroscopically polar crystals.
