In the structure of the title compound, C 16 H 18 N 2 O 4 , intermolecular N-HΓ Γ ΓO [NΓ Γ ΓO = 2.866 (3) A Λ] and O-HΓ Γ ΓO [OΓ Γ ΓO = 2.611 (3) A Λ] hydrogen bonds link molecules into a two-dimensional framework. The crystal structure is further stabilized by weak intermolecular C-HΓ Γ ΓO interact
The title compound, C 19 H 17 N 3 O 3 ΓCH 3 OH, was synthesized by the reaction of 4-amino-1,5-dimethyl-2-phenyl-1,2-dihydropyrazol-3-one and 4-formylbenzoic acid in methanol solution. As expected, the antipyrine derivative adopts a trans configuration about the central C N bond. In the crystal stru
