Abstract
An unexpected mechanism of halogen bonding that cannot be rationalized within the accepted sigma-hole model was found in the co-crystal of N-methylpyrazine iodide with molecular iodine via the topological analysis of the electron density distribution derived from the high-resolution X-ray diffraction data.
摘要
通过对高分辨率 X 射线衍射数据导出的电子密度分布的拓扑分析，在 N-甲基吡嗪碘化物与分子碘的共晶中发现了一种不能用已接受的 σ-hole 模型来合理化的卤键的意外机制。
