在有限的空间中排列物体时,被排列物体的几何因素对排列方式会产生影响。我们将这种效应称为“堆积效应”。用积木游戏可形象说明堆积效应。如在一个圆形积木盒中放进四块圆积木(图1),显然这些积木不能任意排列。积木B只能分别置于积木A的两侧。它们“摄动”的范围是很小的。同样,在配位化合物的分子结构中,配位空间只有4π立体角, When arranging objects in a limited space, the geometry of the objects being arranged affects the arrangement. We call this effect “stacking effect.” With the building blocks game image can be stacked effect. If you put four round bricks in a circular box (Figure 1), it is clear that these bricks can not be arranged randomly. Block B can only be placed on each side of Block A. Their range of “perturbation” is small. Similarly, in the molecular structure of coordination compounds, coordination space is only 4π solid angle,
