The reaction between 5-chloro-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde and phenylhydrazine proceedsviacondensation to provide the title compound, C17H15ClN4, (I), rather thanviathe alternative routes of simple nucleophilic substitution or cyclocondensation. With the exception of the phenyl group bonded directly to the pyrazole ring, the non-H atoms of (I) are nearly coplanar, with an r.m.s. deviation of 0.058 Å. The molecules are linked intoC(7) chains by a single N—H...N hydrogen bond, and the chains are linked by π–π stacking interactions to form sheets.
