1,1′,5,5′-Tetramethyl-2,2′-diphenyl-4,4′-[p-phenylenebis(methylidynenitrilo)]di-1H-pyrazol-3(2H)-one
Abstract
In the centrosymmetric title compound, C30H28N6O2, the dihedral angles between the antipyrine ring and the terminal phenyl and central benzene rings are 50.55 (10) and 14.62 (9)°, respectively. Some short intermolecular C—H...O interactions may help to establish the packing. An intramolecular C—H...O hydrogen bond is also present.
