摘要: The structure of the title compound, C19H17BrN2O3, consists two cyclic groups, viz. 4-(methoxycarbonyl)phenyl and 6-(4-bromophenyl)-3-oxo-2,3,4,5-dihydropyridazin-4-yl, which are linked by a methylene spacer. pyridazine ring is twisted dihedral angle between its mean plane that bromophenyl 17.2 (2)°. group shows quasi-planar conformation, where planes phenyl carboxylate ester 7.9 (4)°. Centrosymmetric intermolecular N—H⋯O hydrogen bonds form dimers. These C—Br⋯O=C interactions [Br⋯O = 3.10 (1) A] to one-dimensional polymeric running along [1\overline{2}0] direction.
