N -(2,6-Dichlorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide

Crystals of the title compound, C 12 H 8 Cl 2 N 2 O 2 , were obtained by slow evaporation of an ethanolic solution. An intramolecular amide N—H...O=C lactam hydrogen bond is observed. In the crystal, two molecules pair up to form a centrosymmetric lactam–lactam dimers (LLD) by N—H...O=C hydrogen bon...

Summary:Crystals of the title compound, C 12 H 8 Cl 2 N 2 O 2 , were obtained by slow evaporation of an ethanolic solution. An intramolecular amide N—H...O=C lactam hydrogen bond is observed. In the crystal, two molecules pair up to form a centrosymmetric lactam–lactam dimers (LLD) by N—H...O=C hydrogen bonds, whereas the O=C amide group of the molecule does not participate in hydrogen bonding.
