Abstract
The asymmetric unit of the title compound, [Fe(C3H4N2)6]SO4·2C3H4N2, contains two complex cations, two sulfate anions and four imidazole molecules. In both cations, the FeII atom is coordinated by six monodentate imidazole ligands and exhibits a slightly distorted octahedral coordination geometry. The Fe—N distances [2.184 (4)–2.218 (4) Å] point to a high-spin state of the Fe2+ ions. N—H⋯O hydrogen bonds between the ionic components generate a three-dimensional framework containing corrugated channels along [001], which are filled by N—H⋯N hydrogen-bonded imidazole chains.
