Mr. (Miss or Mrs.) Sapay, in the same system catalog where are your *.hkl (*.raw), *.lis and *.res files which you use for solving the structure (employing Appex).

Dear Nayim, If you are using APEX-2/WINGX then you are likely using SHELX for structure refinement. Once your structure is fully refined (you have found all your atoms, added H atoms, refined the non-H atoms anisotropically and finally included the recommended WGHT scheme then you can add the ACTA line to your *.ins file which generates a filenm.cif file which is what you need to deposit your structure. However you will need to edit into the cif some of the experimental details which should be in your filenm.pcf file which APEX-2 will have generated.These include the instrument, the measuring strategy, how many reflections were used for cell indexing etc. When you think your cif is complete you should run it through checkcif:

If checkcif identifies any ALERT A or ALERT B (and ideally most ALERT C) errors in your cif, you should correct your cif and re-check it until these errors disappear. Your cif file is then ready for deposit. If it is for a journal check the journal directions carefully. Some journals like you to deposit the structure with the Cambridge Structural Database, others like you to submit the cif as ESI (or both!). You can deposit your structure here:

Thank you Ivanova and Rawson for your kind response. I will try as you say Rawson. If I face any problem I will ask you. I am beginner. Thanks again.
