The title compound, C16H16N4O2, crystallizes with two mol-ecules in the asymmetric unit, one of which shows disorder of the acetate group over two sets of sites in a 0.799 (2):0.201 (2) ratio. The phenyl group has a similar but opposite sense of twist relative to the pyrazole ring in the two mol-ecules, as indicated by the syn N-N-Car-Car (ar = aromatic) torsion angles of 39.7 (2) and -36.9 (2)°. Each mol-ecule features an intra-molecular N-H⋯O hydrogen bond, which closes an S(6) ring. In the cr ...[more]
