<p class=""><span style lang="EN-US">Yes, they
are equivalent by a lattice translation but intermediate images are not
equivalent, because they are set between the first image and a last image,
different from the one I selected. I get “strange” structures of the
intermediate images. I still have 2 CO molecules, but one is in my supercell,
and the other is splitted, the C atom is in the supercell I built and the O
atom is in the next one.</span></p>

<div class="im">> How can I deal with this problem?<br>
<br>
</div>are you sure it is a problem? are the two positions, the original<br>
and the modified one, really different, i.e. not equivalent by a<br>
lattice translation?<br>
