The OXT atom in the restraints file is there because it can be in the
model. You need to remove the atom from the model if you don't want it.

Also, Coot's make link does not make a link in Phenix. You need to rely on
the automatic linking or provide your own. You can check that the link is
present in the refinement by checking the .geo file.

Cheers

Nigel
