We report a σ + π double aromatic CBS cluster, the first global minimum unusually having a planar hypercoordinate carbon inside a boron wheel. Five peripheral sulfur atoms stabilize the carbon-centered boron wheel by weakening the electron deficiency of the boron atoms through strong S → B π back-bonding.
我们报道了一种σ + π双芳香性的CBS簇合物，这是首个全局最小值，其异常之处在于硼轮内部存在一个平面型的超配位碳。五个外围硫原子通过强S→B π反馈键合削弱硼原子的电子缺欠，从而稳定以碳为中心的硼轮。
