Abstract
In the title compound, C17H15FN2O, the pyrazoline ring adopts a flattened envelope conformation. The dihedral angle between the fluoro-substituted benzene ring and the phenyl ring is 69.20 (5)°. In the crystal, a pair of C—H⋯O hydrogen bonds link neighbouring molecules, forming an inversion dimer. The crystal structure is further consolidated by C—H⋯π interactions and by a π–π interaction with a centroid–centroid distance of 3.7379 (6) Å.
Highlights
Cg1 and Cg2 are the centroids of the pyrazole N1/N2/C7–C9 ring and the phenyl C10–C15 ring, respectively
