2-[4-(2-Chlorobenzyl)-3-methyl-6-oxo-1,6-dihydropyridazin-1-yl]-N-(4-fluorophenyl)acetamide

Abstract

The conformation of the title molecule, C20H17ClFN3O2, is partly determined by an intramolecular C—H...O hydrogen bond, which leads to a dihedral angle of 14.7 (4)° between the fluorobenzene ring and the acetamide group. The 2-chlorobenzyl group is rotationally disordered over two orientations in a 0.656 (2): 0.344 (2) ratio. In the crystal, a layered structure is formed by N—H...O, C—H...O and C—H...F hydrogen bonds plus slipped π–π stacking interactions.
