Abstract

The title compound, (C3H5N2)2[Fe(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.
