Methyl 4-{[6-(4-bromo-phen-yl)-3-oxo-2,3,4,5-tetra-hydro-pyridazin-4-yl]methyl}benzoate.

ABSTRACT: The structure of the title compound, C(19)H(17)BrN(2)O(3), consists of two cyclic groups, viz. 4-(meth-oxy-carbon-yl)phenyl and 6-(4-bromo-phen-yl)-3-oxo-2,3,4,5-dihydro-pyridazin-4-yl, which are linked by a methyl-ene spacer. The pyridazine ring is twisted and the dihedral angle between its mean plane and that of the bromo-phenyl mean plane is 17.2?(2)°. The 4-(meth-oxy-carbon-yl)phenyl group shows a quasi-planar conformation, where the dihedral angle between the mean planes of the phenyl ring and carboxyl-ate ester group is 7.9?(4)°. Centrosymmetric inter-molecular N-H?O hydrogen bonds form dimers. These are linked by C-Br?O=C inter-actions [Br?O = 3.10?(1)?Å] to form a one-dimensional polymeric structure running along the [1[Formula: see text]0] direction.
