Abstract

Abstract The compound 1-phenyl-3-methyl-4-benzoylpyrazolon-5-one with the molecular formula C17H14N2O2, exists in a keto-enamine tautomeric form. The pyrazolone ring makes dihedral angles of 28.36 (3) and 59.31 (5) º with the two phenyl rings. The molecules are linked into two-dimensional supramolecular structure by a combination of NH··· O and CH··· O hydrogen-bonding interactions.
