I think you can do what you want using elbow.builder in phenix with a
smiles string.
You can use something like this to make the cofactor:

Then use elbow.builder to make the pdb and cif files, and do your
refinements in phenix.
It may be possible to script all that from within coot, but probably is
not worth the effort.
