(E,E)-3,3′-Dimethyl-1,1′-diphenyl-4,4′-{[3-azapentane-1,5-diylbis(azanediyl)]bis(phenylmethylidyne)}di-1H-pyrazol-5(4H)-one

The asymmetric unit of the title compound, C38H37N7O2, contains one half-molecule, situated on a twofold rotational axis, in which one amino group is involved in intramolecular N—H...O hydrogen bond and the two phenyl rings are twisted from the plane of pyrazolone ring by 26.69 (10) and 79.64 (8)°. The crystal packing exhibits no classical intermolecular contacts.
