它们的化学组成完全相同[P(NH_3)_2Cl_2],但空间结构不同,产生了两种变体在性质上的差异。因此,称这两种变体互为异构体。因为络合物的几何异构是由不同的配位体在空间排布的位置不同而导致的,显然,几何异构体的数目与络合物的几何构型及其中心离子的配位数和配位体的种类直接相关。要确定几何异构体的数目,就必须花费较 Their chemical composition is exactly the same [P (NH_3) _2Cl_2], but the spatial structure of different, resulting in two variants in the nature of the difference. Therefore, we call these two variants each other isomers. Because the geometric heterogeneity of the complexes is caused by the different positions of the different ligands in the space, it is clear that the number of geometrical isomers and the geometry of the complex and the coordination number of its central ion And the type of ligand is directly related. To determine the number of geometric isomers, you have to spend more
