Abstract

The title compound, C19HI8FeN2 or [Fe(CsHs)(CI4HI3-N2)], crystallizes in space group P2~/n with two molecules in the asymmetric unit.The pyrrole groups take part in intermolecular (pyrrole)N--H...Tr(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)/k and N--H.--(pyrrole centroid) angles in the range 127-139 °.
