Thank you! Yep, they seem to be wanting to bond to the O's within the cell, while they are meant to bond across the PBC.
I am not sure how periodic_molecule = yes part functions. I don't seem to get difference if I turn it on or off when I do Energy minimisation. Do you have some examples that work, so I can compare to them? Are there some threshold distances, that they rely upon? I really wouldn't like to have to make the a bigger basic cell - too much topology assigning.
