Thanks dear Elmar and Eric. Infect am not an expert I am synthesizing single crystal and then sent for SXRD, then I got my solved data there are some information in cif i dont understand
Arshad: I once made commented CIF with the description of individual entries for my students as a part of the textbook. It is in Slovak, but however if you are interested, maybe I can try to make English version.
Most crystallography programs should allow you to produce tables or reports on your CIF. Who ever did your crystallography for you should be able to do this for you in a matter of seconds.
The crystallography books may not necessarily teach you much about CIFs although a basic understanding will allow you to understand the CIF information more easily.
