چکیده
The title heteroaryl chalcone derivative, C(17)H(17)NO(4), is a condensation product of 2-acetyl-pyridine and 2,4,6-trimeth-oxy-benzaldehyde. The mol-ecule is roughly planar, the dihedral angle between the pyridine and benzene rings being 5.51 (10)°. All the three meth-oxy groups are almost co-planar with the bound benzene ring [r.m.s. deviation of 0.0306 (2) Å]. A weak C-H⋯O intra-molecular inter-action involving one of the ortho-meth-oxy groups generates an S(6) ring motif. In the crystal, the mol-ecules are linked by weak C-H⋯O inter-actions into anti-parallel face-to-face pairs. Adjacent pairs are further connected into sheets parallel to the ab plane.

The mean planes of the benzene and pyridine rings in the title compound, C(15)H(12)BrNO(2), are nearly coplanar, subtending an angle of 2.8 (8)°. The prop-2-en-1-one group is also in the plane of these rings with an N-C-C-O torsion angle of 179.6 (3)°. A weak C-H⋯Br inter-molecular inter-action contributes to the crystal packing, creating a chain-like structure along the a axis.
