title: (E,E)-3,3'-Dimethyl-1,1'-diphenyl-4,4'-{[3-aza-pentane-1,5-diylbis(aza-nedi-yl)]bis-(phenyl-methyl-idyne)}di-1H-pyrazol-5(4H)-one.
abstract: The asymmetric unit of the title compound, C(38)H(37)N(7)O(2), contains one half-mol-ecule, situated on a twofold rotational axis, in which one amino group is involved in intra-molecular 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 inter-molecular contacts.
