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 R22(10), C(6), C(7), C(7), and R44(28), respectively.
