Also, ich hab jetzt mal in der Diamond-Hilfe nachgeschaut, da kommt dann folgende Anleitung (sogar am Beispiel eines Cyclopentadienylringes):
- To define a dummy atom - for example in the center of a cyclopentadienyl ring -, follow these steps:
1. Build up the structure as described in the previous chapters. (For the above example, make use of the molecule function.)
2. Select the five C atoms of the cyclopentadienyl ring, and then choose the Insert atom command from the Structure menu. This will open the Insert atom dialog, like in the following example:
3. Change the atom symbol, which is "Dummy" by default (or "Dummy2" for the second dummy atom, etc.), if you want, and then confirm with OK.
4. Choose the Atom types command from the Edit menu, which opens the Atom types dialog, if you want to change the shape of the dummy atom. (See "Designing Atoms and Atom Types: Overview" how to edit atom types.)
How to connect the dummy atom with the praseodym atom like in the picture, see the article "Inserting a Bond Between Two Atoms
". To make the bond "fragmentated", read the article "Fragmentated Bonds".
