Chemical bonding is the language of logic for chemists. Two new resonance bonding models, ω-bonding and charge-shift (CS) bonding, are gaining popularity among chemists. This study investigated the Cu/Ag/Au bonding in BMX (B = H2O, H2S, NH3, and PH3; M = Cu, Ag, and Au; and X = F, Cl, Br, and I) complexes using natural bond orbital (NBO) analysis, natural resonance theory (NRT), and atoms in molecules (AIM) method. The main aim is to reveal the relation between ω-bonding model and CS bonding model via Cu/Ag/Au bonding. Our studies demonstrate that the Cu/Ag/Au bonds exhibit the characteristics of both ω-bonding and CS bonding. Further studies found that ω-bonding and CS bonding models are equivalent and complement each other in understanding the studied Cu/Ag/Au bonding. Another interesting finding is the implication of the omega symbol in the ω-bonding model. These findings could help to promote the communication and CS bonding understanding of many more similar ω-bonded complexes.

ω-键合模型和电荷转移键合模型的等效和互补:通过 BMX 中的 Cu/Ag/Au 键合研究自然键轨道/自然共振理论/分子中的原子(B = H2O、H2S、NH3 和 PH3; M = Cu、Ag 和 Au;X = F、Cl、Br 和 I)

化学键是化学家的逻辑语言。两种新的共振键合模型,ω 键合和电荷转移 (CS) 键合,越来越受到化学家的欢迎。本研究调查了 BMX 中的 Cu/Ag/Au 键合(B = H 2 O、H 2 S、NH 3和 PH 3; M = 铜、银和金;和 X = F、Cl、Br 和 I) 配合物使用自然键轨道 (NBO) 分析、自然共振理论 (NRT) 和分子中的原子 (AIM) 方法。主要目的是通过 Cu/Ag/Au 键合揭示 ω 键合模型与 CS 键合模型之间的关系。我们的研究表明,Cu/Ag/Au 键表现出 ω 键和 CS 键的特征。进一步的研究发现,ω-键合和 CS 键合模型在理解所研究的 Cu/Ag/Au 键合方面是等效的并且相互补充。另一个有趣的发现是欧米茄符号在 ω 键合模型中的含义。这些发现可能有助于促进对更多类似 ω 键合复合物的交流和 CS 键合理解。
