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.

摘要

标题杂芳基查尔酮衍生物C(17)H(17)NO(4)是2-乙酰基吡啶与2,4,6-三甲氧基苯甲醛的缩合产物。分子大致呈平面状，吡啶环与苯环之间的二面角为5.51 (10)°。所有三个甲氧基几乎与相连的苯环共平面[r.m.s.偏差为0.0306 (2) Å]。涉及一个邻位甲氧基的弱C-H⋯O分子内相互作用形成了一个S(6)环模式。在晶体中，分子通过弱C-H⋯O相互作用连接成反平行的面对面二聚体。相邻的二聚体进一步连接成平行于ab平面的片层。
