RESUMEN
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 77.92â (3)°. The pyrazolidine ring adopts an envelope conformation. An intra-molecular C-Hâ¯N hydrogen bond results in the formation of a five-membered ring adopting an envelope conformation. In the crystal structure, inter-molecular N-Hâ¯O and C-Hâ¯O hydrogen bonds link the mol-ecules. There are C-Hâ¯π contacts between between aromatic H atoms and the phenyl and fluorophenyl rings. A π-π contact between phenyl rings [centroid-centroid distance = 3.926â (1)â Å] is also observed.
RESUMEN
