Abstract

The bond distances in the molecule of the title compound, C(19)H(14)N(2)O(4), provide evidence for electronic polarization in the aminoarylpropenone fragment and for bond fixation in the quinolinone unit. Molecules are linked by N-H...O and C-H...O hydrogen bonds into chains in which centrosymmetric rings of R(2)(2)(8) and R(2)(2)(18) types alternate, and these chains are linked into sheets by a single aromatic pi-pi stacking interaction.

摘要

标题化合物C(19)H(14)N(2)O(4)分子中的键长为氨基芳基丙烯酮片段中的电子极化以及喹啉酮单元中的键固定提供了证据。分子通过N-H...O和C-H...O氢键连接成链，其中R(2)(2)(8)和R(2)(2)(18)类型的中心对称环交替出现，并且这些链通过单一的芳香π-π堆积相互作用连接成片。
