4-[(Ethoxyimino)(phenyl)methyl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one

Abstract

In the molecule of the title compound, C19H19N3O2, the central pyrazole ring makes dihedral angles of 9.89 (3) and 66.06 (5)° with the two phenyl rings, and the two phenyl rings form an angle of 74.05 (5)°. An intramolecular C—H...O hydrogen bond forms a six-membered ring, producing an S(6) ring motif. In the crystal structure, intermolecular N—H...O and C—H...O hydrogen bonds link each molecule to two others, forming an infinite one-dimensional supramolecular structure along the c axis.
