Abstract : The title Schiff base compound, C23H23N5O, was synthesized by the reaction of 4-amino-phenazone and 3,5-dimethyl-1-phenyl- pyrazole-4-carbaxaldehyde. The molecule adopts an E configuration about the central C=N double bond. A weak intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The dihedral angle between the pyrazole rings is 24.72 (10)° and the dihedral angles between the pyrazole rings and the adjacent phenyl rings are 58.67 (10) and 46.58 (11)°. The crystal structure is stabilized by weak C-H⋯π inter-actions involving the pyrazolone and phenyl rings.
