A second polymorph of (Z)-3-amino-4-(2-phenylhydrazinylidene)-1H-pyrazol-5(4H)-one
The molecule of the title compound, C(9)H(9)N(5)O, is approximately planar (the r.m.s. deviation of all non-H atoms is 0.08 Å). The amine substituent is pyramidal at the N atom. An intramolecular N—H(hydrazine)⋯O=C hydrogen bond is present. In the crystal, molecules are connected via N—H⋯N and N—...
