title: (2E)-1-(Pyridin-2-yl)-3-(2,4,6-trimeth-oxy-phen-yl)prop-2-en-1-one.
abstract: 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.
