Abstract
The title Schiff base compound, C22H24IN3O2, adopts an E configuration about the central C=N bond. The pyrazolone ring makes a dihedral angle of 49.68 (10)degrees with its attached phenyl ring. The phenolate plane makes dihedral angles of 16.78 (9) and 50.54 (9)degrees, respectively, with the pyrazolone ring and the terminal phenyl ring. An intramolecular C-H center dot center dot center dot O hydrogen bond generates an S(6) ring motif. In the crystal structure, an intermolecular C-H center dot center dot center dot O hydrogen bond is also observed.
