Creating a Multi-Center Bond

---

To create a multi-center attachment point:

1. Select the structure whose center you want defined as a multi-center attachment point.

2. From the Structure menu, choose Add Multi-Center 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.

To make the bond in ferrocene appear that it is coming from within the ring:

1. Double-click the wedged bond to make it come forward.

2. Select the downward bond.

3. Double-click on the cyclopentadienyl ring with a selection tool.

The entire structure, including the single bond, is selected. The Cp ring and the single bond are associated as one structural unit because ChemDraw recognizes the bond between them.

NOTE: For the best looking structure, you may need to draw a longer than normal bond. You can toggle the Fixed Length command by typing Command+L.
