謝謝大家?guī)椭�了~

先用模板畫一個(gè)茂環(huán)，然后選中。
菜單：Structure>Add MultiCenter Attachment
茂環(huán)中心出現(xiàn)一個(gè)星。
從星引出一個(gè)單鍵，此時(shí)星就消失了。把單鍵的另一端定義為Fe.

然后，再用模板畫一個(gè)茂環(huán)，然后選中。
菜單：Structure>Add MultiCenter Attachment
第2個(gè)茂環(huán)中心出現(xiàn)一個(gè)星。
畫一個(gè)單鍵，把這個(gè)星與Fe連起來。

下面是ChemDraw的幫助：

To create a multi-center attachment point:

1. Select the structure whose center you want defined as a multi-center attachment point.
2. Go to Structure>Add MultiCenter Attachment.

An asterisk is displayed with the fragment to show that it contains a multi-center node.

The asterisk is not visible once a bond is drawn to it. You can view the attachment point with a bond or selection tool. For more information, see Viewing Attachment Points.

To draw a bond to a multi-center attachment point:

1. Click the Bond tool.
2. Point to the asterisk and either click or drag to create a bond.
  
Tip:  Go to Objects>Fixed Lengths to either disable or toggle Fixed Lengths to draw the bond so that it extends from the ring，

但這樣 分析H怎么是12個(gè)呢

樓上的畫法可以，但好像還是沒有解決無法再chemdraw里顯示二茂鐵的HNMR和將結(jié)構(gòu)轉(zhuǎn)化為名稱
