The title compound, C2H10N22+·2C10H9N2O−, is composed of deprotonated 5-methyl-2-phenyl-1H-pyrazol-3(2H)-one anions (PMP−) and protonated ethylenediamine cations (H2en2+). The ethylenediammonium ion is located on a crystallographic inversion center. The dihedral angle between the phenyl and pyrazole rings is 39.73 (8)°. The two components are connected through N—H...O and N—H...N hydrogen bonds, forming an infinite three-dimensional network.
