Dear Akansha Agarwal many thanks for sharing this interesting technical question with the RG community. Certainly the most efficient and popular tools for solving and refining single-crystal X-ray diffraction data are the programs developed by George M. Sheldrick (e.g. SHELX and SHELXL). For general information about this software please have a look at the following article:

In my personal exerience you cannot learn single-crystal X-ray crystallography by studying a few articles. If you do not have long-standing practical experience in this field, I would strongly suggest to collaborate with an experienced crystallographer.
Good luck with your work and best wishes, Frank Edelmann
