title: (Z)-4-[2-(2,4-Dimethyl-phen-yl)hydrazinyl-idene]-3-methyl-pyrazol-5(1H)-one.
abstract: The mol-ecule of the title compound, C12H14N4O, is roughly planar, with a dihedral angle of 8.0 (8)° between the benzene and pyrazole rings, and an intra-molecular N-H⋯O hydrogen bond forms an S(6) ring motif. In the crystal, mol-ecules are linked into an inversion dimer by a pair of N-H⋯O hydrogen bonds, which form an R 2 (2)(8) ring motif.
