title: 1,1',5,5'-Tetra-methyl-2,2'-diphenyl-4,4'-[p-phenyl-enebis(methyl-idynenitrilo)]di-1H-pyrazol-3(2H)-one.
abstract: In the centrosymmetric title compound, C(30)H(28)N(6)O(2), the dihedral angles between the anti-pyrine ring and the terminal phenyl and central benzene rings are 50.55 (10) and 14.62 (9)°, respectively. Some short inter-molecular C-H⋯O inter-actions may help to establish the packing. An intramolecular C-H⋯O hydrogen bond is also present.
