The title compound, C 20 H 17 BrN 2 O 4 , contains a fourmembered -lactam ring; the 2,5-dioxopyrrolidin-1-yl and 4bromophenyl groups are in cis positions.
In the structure of the title compound, C 16 H 18 N 2 O 4 , intermolecular N-HÁ Á ÁO [NÁ Á ÁO = 2.866 (3) A ˚] and O-HÁ Á ÁO [OÁ Á ÁO = 2.611 (3) A ˚] hydrogen bonds link molecules into a two-dimensional framework. The crystal structure is further stabilized by weak intermolecular C-HÁ Á ÁO interact
The title compound, C 10 H 9 N 3 O 2 S, crystallizes in the orthorhombic non-centrosymmetric space group P2 1 2 1 2 1 . The molecules are linked into a three-dimensional network through OÐHÁ Á ÁN and NÐHÁ Á ÁO hydrogen bonds and weak SÁ Á ÁO interactions.
The title compound, C 19 H 17 N 3 O 3 ÁCH 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
