<div>
<p class="MsoNormal">Dear Eduardo,<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">thank you very much for your e-mail, for offering your work for COD, and my big apologies for not responding earlier.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Your structure seems to be the all time record at the COD :); all structures deposited so far seem to fit the previous 2M limit. I have thus increased the upload limit to 20M, so that your structure can be uploaded both zipped and unzipped
(as a plain CIF file). Please check if this works for you.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I have also looked into the CIF itself (just to see if the upload problem was not related to the content itself). May I suggest several changes to the CIF:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">1) The original file file contained characters with diacritics ("ü" in "_computing_molecular_graphics 'shelXle (Hübschle, Sheldrick and Dittirch, 2011)'"), entered in the Latin1 encoding. Such characters are not permitted in the CIF standard
and are in fact ambiguous. While our COD software will change them to a CIF compliant sequence using an XML entity, I suggest that a better encoding is used – the CIF escape sequence ('H\"ubschle' instead of 'Hübschle'). If you accept this suggestion, I have
prepared a file under a private link with this change [1] link for your convenience;<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">2) certain disorder groups generate atoms that have steric clashes when interpreted as distinct molecules. The disorder is notoriously tricky to mark up in CIF, especially since you have disorder around a special position for one water
molecule. If you would agree with such interpretation of your structure, I have prepared the file with the new disorder markup [2]; I also attach detailed descriptions of the changes ("notes-SG.txt"), which you may want to ingest into your work flow. This
new markup gives chemically complete molecules when they are generated from each disorder assembly (at least with our software), so would be beneficial IMHO.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">3) finally, I have noticed that one atom, C15", lacks hydrogen atoms, but seems to need them, being a methylene bridge (it is an alternative conformation of the C15F that does have two hydrogens attached). May I suggest that you model hydrogens
on C15", so that every disorder group has the same composition? This can be done in two ways:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">3a) Adding the hydrogens model explicitly and re-running SHELX analysis to get the (slightly) updated statistics (R-factors et al.);<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">3b) Adding the new data name to the coordinate loop, '_atom_site_attached_hydrogens', specifying '.' for all atoms except the C15" atom, and giving value '2' for the '_atom_site_attached_hydrogens' of atom C15". This would formally not
require re-computation of R-factors. I have prepared an example of such encoding in [3].<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The change suggested in (3) would add one hydrogen to your structure (2 half occupied H sites), and thus change the formula from 'C254
<b><i>H404</i></b> N14 O72 U8' to 'C254 <b>H405</b> N14 O72 U8'. The latter formula, however, would agree with individual formulae of each disordered assembly collection:<o:p></o:p></p>

<div>
<p class="MsoNormal">What would be you opinion on the suggested interpretation of the structure? Adding all hydrogens and marking the special position disorder would allow to generate chemically uncontroversial models of all components in your crystal, which
would be IMHO of interest for chemists :)<o:p></o:p></p>
