Five (1H‐pyrrol‐2‐yl)­pyridines

The title (1H‐pyrrol‐2‐yl)­pyridines, C₉H₈N₂, substituted at the ortho, meta, and para positions of the pyridine ring all have hydrogen‐bonded arrangements with geometrically similar, nearly linear, N(pyrrole)—H⋯N(pyridine) hydrogen bonds of average length. The graph sets for the ortho, meta, and three para polymorphs are R(10), C(6), C(7), C(7), and R(28), respectively.
