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_2^ 2 (10), C (6), C (7), C (7), and R_4^ 4 (28), respectively.
