Information Gain from Density-Based Reactivity Theory Reveals Charge-Shift Bonding in Real Space

Xiaoyan An, Tian Lu, Tingzhen Chen, Chen Zhou et autres

Charge-shift bonding (CSB), in which stabilization arises primarily from resonance between covalent and ionic structures rather than simple electron sharing, challenges the traditional covalent-ionic paradigm of chemical bonding. However, its identification has so far relied on either the resonance-energy-based analysis within valence …
