配合物的配位数同为四,为什么有的配合物的空间构型为正四面体,有的为平面正方形呢?在价键(杂化)理论中明确地指出:SP~3杂化的构型为正四面体,dsp~2杂化的构型为平面正方形,这是为什么?对此,价键理论难以圆满解释。配位化学几何构型的定性描述是依据电子对之间的排斥作用来说明,为了使各配位体之间(亦即成键电子对之间)的相互排斥力为最 The coordination number of the complexes is the same as four. Why is the space configuration of some complexes in the form of regular tetrahedron and some in the plane square? It is clear from the theory of valence bond (hybridization) that SP3 hybrid The structure is a regular tetrahedron, dsp ~ 2 hybrid configuration for the plane square, which is why? In this regard, the key theory is difficult to satisfactorily explain. The qualitative description of the coordination chemistry geometry is based on the repulsion between pairs of electrons. In order to make the mutual repulsion between each ligand (ie, the pair of bonding electrons)
