Abstract

In the crystal, mol-ecules of the title compound, CHFINOS, are connected through C-H⋯N and C-H⋯O hydrogen bonds, I⋯O halogen bonds, π-π stacking inter-actions between the benzene and pyrimidine rings, and edge-to-edge electrostatic inter-actions, as shown by the analysis of the Hirshfeld surface and two-dimensional fingerprint plots, as well as inter-molecular inter-action energies calculated using the electron-density model at the HF/3-21 G level of theory.

摘要

在晶体中,标题化合物CHFINOS的分子通过C-H⋯N和C-H⋯O氢键、I⋯O卤键、苯环与嘧啶环之间的π-π堆积相互作用以及边对边静电相互作用相连,这是通过对Hirshfeld表面和二维指纹图谱的分析以及使用HF/3-21 G理论水平的电子密度模型计算的分子间相互作用能所表明的。
