The title compound, C₁₉H₁₈FeN₂ or [Fe(C₅H₅)(C₁₄H₁₃-
N₂)], crystallizes in space group P2₁ln with two molecules
in the asymmetric unit. The pyrrole groups take
part in intermolecular (pyrrole)N--H...π(pyrrole) interactions
through a hydrogen-bonded ring system involving
four pyrrole groups, with N..-(pyrrole centroid)
distances in the range 3.209(3)-3.427 (3)Å and N--
H...(pyrrole centroid) angles in the range 127-139°.
