چکیده
In the mol-ecule of the title compound, C(15)H(13)FN(2)O, the phenyl and fluorophenyl rings are oriented at a dihedral angle of 77.92 (3)°. The pyrazolidine ring adopts an envelope conformation. An intra-molecular C-H⋯N hydrogen bond results in the formation of a five-membered ring adopting an envelope conformation. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules. There are C-H⋯π contacts between between aromatic H atoms and the phenyl and fluorophenyl rings. A π-π contact between phenyl rings [centroid-centroid distance = 3.926 (1) Å] is also observed.
