Abstract
The title compound, C15H13ClN4, crystallizes with two independent molecules (AandB) in the asymmetric unit, which are far from planar as a result of steric repulsion between the rings. The benzene and phenyl rings are inclined to the central pyrazole ring by 46.64 (10) and 17.87 (10)° in moleculeA, and by 40.02 (10) and 14.18 (10)° in moleculeB. The aromatic rings are inclined to one another by 58.77 (9)° in moleculeA, and 36.95 (8)° in moleculeB. In the crystal, theAandBmolecules are linked by two pairs of N—H...N hydrogen bonds formingA–Bdimers. These are further linked by a fifth N—H...N hydrogen bond, forming tetramer-like units that stack along thea-axis direction, forming columns, which are in turn linked by C—H...π interactions, forming layers parallel to theacplane.
