The sulphur atom in the intermediate has sp2 hybridization, and the remaining p orbital is symmetrical to the d orbital of the metal center. Thus, the lone pair on the p orbital can have interaction with the d orbital to form a π bond, which leads to the coplanarity of the center of Cp ring, Ru, P, S and Si atoms, rather than the deviation of P, S and Si atoms from the plane.

该中间体中，硫原子采取sp2杂化，硫原子剩余的一个p轨道与金属中心上的d轨道具有相同的对称性，因而该p轨道上的孤电子对可与金属中心上的d轨道形成π键，导致Cp环中心， Ru， S1， P和Si原子在同一平面内，而不是S1， P和Si原子偏离该平面。

In 1791, Volta was the Royal Society Copley Award, and was elected to the Royal Society.
