The cation complexes [ArBO], [ArBO], [ArBO] and [ArBO] were prepared a laser vaporization supersonic ion source in the gas phase. Their vibrational spectra were measured mass-selected infrared photodissociation spectroscopy. Spectroscopy combined with quantum chemical calculations revealed that the [ArBO], [ArBO] and [ArBO] cation complexes have planar structures each involving an aromatic boroxol ring and an argon-boron covalent bond. In contrast, the [ArBO] cation is characterized to be a weakly bound complex with a BO chain structure.
阳离子配合物[ArBO]、[ArBO]、[ArBO]和[ArBO]是在气相中通过激光蒸发超声离子源制备的。它们的振动光谱通过质量选择红外光解离光谱进行测量。光谱学与量子化学计算相结合表明,[ArBO]、[ArBO]和[ArBO]阳离子配合物具有平面结构,每个结构都包含一个芳族硼氧环和一个氩-硼共价键。相比之下,[ArBO]阳离子的特征是具有BO链结构的弱结合配合物。
