<p class="MsoNormal"><span lang="DE">Dear Sirs,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="DE"><o:p> </o:p></span></p>
<p class="MsoNormal">We are working on a project in which we would need a list of possible known and described (e.g. in COD) crystalline phases.<o:p></o:p></p>
<p class="MsoNormal">The system is inorganic and oxidic and could contain different up, to 5 cations.<o:p></o:p></p>
<p class="MsoNormal">Now I was wondering about the best way to search for available phases e.g.<o:p></o:p></p>
<p class="MsoNormal">for an oxidic system that contains besides oxygen Zn Al Si K Ca
<o:p></o:p></p>
<p class="MsoNormal">Hereby all possible combinations of oxidic structures containing 2 cations, 3 cations… 5 cations should be provided.<o:p></o:p></p>
<p class="MsoNormal">Other anions or cations should be excluded is possible.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I had hoped that by using 1 to 8 elements with the oxygen and the given cations would give me the result if<o:p></o:p></p>
<p class="MsoNormal">I specify the number of distinct elements min and max at 2 and 6 respectively. But that did not work out.<o:p></o:p></p>
<p class="MsoNormal">Maybe I just made a mistake. The O and K was typed with a space before the element and also after it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If you could give me a suggestion how to proceed and search I would be very grateful.
<o:p></o:p></p>
<p class="MsoNormal">If this cannot be done, I would like to provide it as a suggestion.<o:p></o:p></p>
<p class="MsoNormal">Of course one could probably just fix Zn and O and allow up to 6 ions and in a consecutive step one could
<o:p></o:p></p>
<p class="MsoNormal">work on the extracted list using a script but that seems not very straight forward and might lead to a lot of mistakes.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In case of any questions please let me know.<o:p></o:p></p>
