In the structure of 1, CuI ion site between the two CuII ions, which blocks the magnetic coupling of the spin center, so the compound show very weak antiferromagnetic behaviors.

在配合物1中，结构中存在一价铜，并且这个一价铜嵌在所有的二价铜之间，这就阻碍了顺磁离子之间的磁耦合，所以这个配合物呈现出非常弱的反铁磁耦合。

Let's do an example. Let's try to figure out if we have just a uniform disk how hard it is to spin it around its center.

还是看个例子吧，有一张均匀的唱盘，让它绕中心旋转有多难呢？

For example, you can try to measure how hard it is to spin this sheet of paper about an axis that is in the center of it.

比如，试着让一张纸绕其中心轴旋转，看看有多困难。
