Re: atomic position

You might like to add it to COD :-) Sure. Let me a few days to add the 50 crystal structures lacking in the Crystallography Open Database. There is some opposition in the world to attain this target and not a lot of help from the crystallographers themselves (one should ask why :-().

dear everybody, I think there is some misconception here. It is true that the PDF-4+ is a commercial database: this means that sharing the information taken from the database (as recently done here) is an explicit violation of copyrights of ICDD and the violator might be legally prosecuted. When
