The title compound, C(14)H(18)O(4), was obtained unintentionally as the major product of an attempted synthesis of (E,E)-2,5-bis-[2-(2,4,6-trimeth-oxy-phen-yl)ethen-yl]pyrazine. The crystal packing features layers based on two weak C-H⋯O hydrogen bonds involving the O atom of the carbonyl group and two O(meth-oxy)⋯C(meth-oxy) inter-actions [3.109 (2) Å]. The sheets are inter-connected via meth-oxy-meth-oxy dimers and C-H⋯π inter-actions.
标题化合物C(14)H(18)O(4)是在尝试合成(E,E)-2,5-双-[2-(2,4,6-三甲氧基苯基)乙烯基]吡嗪时意外得到的主要产物。晶体堆积以基于两个弱C-H⋯O氢键的层为特征，这两个氢键涉及羰基的O原子以及两个O(甲氧基)⋯C(甲氧基)相互作用[3.109 (2) Å]。这些片层通过甲氧基-甲氧基二聚体和C-H⋯π相互作用相互连接。
