Hi Ed: You do not need to start with a CIF file at all. All you need is the space group, the lattice constants and the atomic positions. You can then fillin the blanks for the Atoms program yourself. Carlo On Mon, 8 Aug 2016, Ed Han wrote:
Hello All,
I apologize in advance if this is not the correct method to reply to the thread.
Thank you for your replies and suggestions. I will look further into determining the atomic structure of the Hf-Al intermetallics through their papers.
Once I obtain this information, how do I go about creating the actual CIF file? Can I just open up any arbitrary CIF file and then change the parameters and name to match that of the Hf-Al systems?
Lastly, going through some CIF files from crystallography.net, I notice that some of the 3D models from the CIF has a different stoichiometry from the designated crystal. For example, I have attached a CIF file of SiO2 that I have found; however, the 3D representation only has 1 Silicon atom and 1 Oxygen atom. Do you have any insight on this disparity?
Regards, Ed Han
