(2E)-1-(Pyridin-2-yl)-3-(2,4,5-tri­meth­oxy­phen­yl)prop-2-en-1-one

The title heteroaryl chalcone derivative, C₁₇H₁₇NO₄, is close to planar: the dihedral angle between the pyridine and benzene rings is 3.71 (11)° and the meth­oxy C atoms deviate from their attached ring by 0.046 (3), −0.044 (2) and 0.127 (3) Å. The disposition of the pyridine N atom and the carbonyl group is anti [N—C—C—O = −177.7 (2)°]. In the crystal, mol­ecules are linked by weak C—H...N and C—H...O inter­actions into (100) sheets and an aromatic π–π stacking inter­action between the pyridine and benzene ring, with a centroid–centroid separation of 3.7036 (14) Å also occurs.
