4-({4-[1-(Methoxyimino)ethyl]anilino}(phenyl)methylene)-3-methyl-2-phenyl-1H-pyrazol-5(4H)-one

Abstract

In the title compound, C26H24N4O2, the dihedral angles between the central pyrazole ring and the other three benzene rings are 40.02 (3), 77.51 (5) and 55.72 (3)°. A strong intramolecular N—H...O hydrogen bond forms a six-membered ring with an S(6) motif. In the crystal structure, a weak intermolecular C—H...N interaction with graph-set motif R22(8) and C—H...O hydrogen bonds link each molecule to three others, forming an infinite two-dimensional supramolecular structure.
