Abstract: | The title compound, (C3H5N2)2Fe(CN)5(C3H4N2)], is composed of a mononuclear Fe(CN)5(pyrazole)]2? dianion and two 1H‐pyrazol‐2‐ium cations. A three‐dimensional supramolecular network is formed through a rich scheme of N—H...N hydrogen bonds and C—H...π interactions among the cations and anions. |
