摘要: The title compound, C10H7F3N2O, is an analogue of pyrazolone derivatives with potential analgesic and anti-inflammatory properties. Its molecular structure consists phenyl pyrazol-3(2H)-one units a dihedral angle between the mean planes rings 33.0 (1)°. crystal stabilized by intermolecular hydrogen bond N—H group carbonyl O atom ring which links molecules into supramolecular C(5) chains along [001] weak π–π stacking interactions [centroid-centroid distance = 3.881 (2) A]. F atoms are disordered over two positions refined site occupancies 0.768(11) 0.232(11).
