Abstract

A gradual change of BrN bond lengths and strengths from the values typical for intermolecular associates to that characteristic of a covalent bond was observed in a series of halogen-bonded complexes. This continuum reveals a fundamental relationship between the limiting types of bonding and implies the onset of covalency in the intermolecular interactions.

摘要

在一系列卤键复合物中，观察到 BrN 键长和键强度逐渐从典型的分子间缔合值变化到共价键特征值。这种连续变化揭示了极限键型之间的基本关系，并暗示了分子间相互作用中共价性的开始。
